    Oh boy; a 21st b'day party in the city that never sleeps. Now why didn't I think of that 30++ years ago?
    Hope you plan to see the Blue Man Group and sit front row, center.

    Removing and reinstalling a connector is an effective way to remove a thin coating of oxidation from the connector pins and mating surfaces. Doing it three or four times is even better. And then we get to the "spray can of contact cleaner" stage.
    Hope you found the issue.

    JimD got a reaction from Joel Siegel in Park brake release - electric   
    This will be specific to what I believe is a limited number of years of Seville models (1998 - 2004?). And more specific to my 1998 model year experience.
    Problem
    Park brake fails to release when gear selector moved from Park.
    One possible Cause
    Oxidation/corrosion on fuse and/or relay plug-in contact blade surfaces.
    Possible Solution
    Remove and reinstall each and every fuse and relay in the underseat Fuse/Relay box; one by one.
    Cost
    Less than one hour.
    Rationale
    This condition has been haunting me for longer than I care to admit; to the point where I stopped using my park brake. Today was the opportunity to properly diagnose the situation. And oxidation was the problem. Unfortunately, I can't specify which fuse/relay blades were oxidized because my Service Manual schematic diagrams conflict with what is acutally installed in my 1998 model car (typical with the first year of a model change).
    Here are operational theory details for the technically inclined

    Your Deville can display DTCs. The instructions used to be on this board but I can no longer find them.
    Memorize this procedure....
    * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
    DTC display; 1998-2004 Seville and 2000-2005 Deville
    Use the 3 switches located to the right of the Driver Information Center (DIC) to activate and respond to the OBD prompts on the DIC.
    ON/OFF = YES
    INFO RESET = NO
    INFO DOWN or INFO UP = manual toggle
    Ignition ON, acknowledge any warning messages; press ON/OFF and INFO UP together for 2 to 3 seconds. Everything in front of you lights up for 4 or 5 seconds, then you will see:
    Display shows "ALL?"
    Answering YES will display "ALL CODES?"
    Answering YES will run automatic test sequence and display codes, if any. Systems and codes will scroll faster than I am able to read them and write them; not to worry.
    "ALL CLEAR CODES?" will display at the end of the automatic test. If you are satisfied you have the information you need, answer YES
    to clear/erase all error codes.
    Answering "ALL?" with INFO DOWN will toggle systems test manually in order.
    Answering "ALL?" with INFO UP will toggle system test manually in reverse order.
    Press INFO RESET to reset DIC to "ALL?" to start again.
    Ignition OFF to exit.
    SYSTEMS: (as of 1998)
    ABS (Antilock Brake System)
    AMP (Amplifier)
    DDM (Door Driver Module)
    DIM (Dash Integration Module)

    At the base of the steering column, almost directly above the brake pedal, you should find a rectangular 6 pin connector that goes to the steering wheel position sensor. Check that connector and the associated wiring for security and possible damage.
    I would try this before throwing parts at the problem; find a vacant parking lot and at low speed, crank the steering wheel full lock in both directions several times while the car is moving. Shut off the engine and clear all the codes. Then see what happens when you drive it normally.
    You need to see the same code or codes repeat to be sure you have a consistent and fixeable problem.

    JimD got a reaction from Texas Jim in How does it work?   
    The Peltier affect is indeed the process used to cool and heat the seats in question.
    The process in the cooling mode is similar to that used in portable drink coolers that utilize a 12 VDC power source.
    In heating mode the Peltier module generates heat that is absorbed by a heat sink. A series of fans circulate air across the heat sink and distribute the warm air throughout the seat.
    In cooling mode the DC voltage input to the Peltier module is reversed and the heat sink is cooled. The same fan arrangement distributes the cool air radiated by the heat sink.

    JimD got a reaction from JohnnyG in Dexron III and a lot of it   
    Exactly.
    In the case of GM, the Dexron standard has been the recommended transmission fluid for as long as I can remember. Likewise Mercon for FOMOCO transmissions. Where is the conspiracy?
    My 2011 GM vehicle Owner's Manual 'recommends' dexos specification engine oil.
    The next paragraph in the manual provides an escape clause like this "In the event that dexos approved engine oil is not available at an oil change or for maintaining proper oil level, you may use a substitute engine oil displaying the API Starburst symbol and of SAE 5W-30 viscosity grade....
    GM maintains a web page listing brands that meet the dexos specification.

    JimD got a reaction from Texas Jim in Question to Everyone: Why Do You Get Periodic Alignments   
    II have been singing that song for years. Maybe the answer is as simple as 'my Daddy told me to have the suspension aligned once a year'. Substitute your favorite role model for Daddy.
    Modern vehicles are engineered to be assembled as efficiently as possible (time = money). To that end, suspension components are designed/manufactured to bolt into place and have the camber/caster geometry within spec's. The mounting holes are not slotted or elongated for adjustment.
    In fact, the only factory provided adjustment is toe in.
    If it ain't broke.....

    JimD got a reaction from Texas Jim in I need info on the AMP for the 2006 DTS with BOSE   
    I get it. But in the passenger compartment there is virtually no space between the rear seat back cushion and the structural member behind the cushion. The modules/components/wire harness are all located on the trunk side of the structural member.
    It appears that GM RPO codes could be year/model specific.
    Back to the missing audio and the possible (likely) audio amplifier channel failure. Certainly a discrete component in one audio channel can fail. If you are willing to wait for diagnosis and repair to your amplifier, do not waste your time expecting anyone other than Bose to do the job properly. The Bose web site should provide information on Bose repair facilities in your area.

    Stay informed about the Colorado wildfire situation and possibly rethink your return route if that route included the front range (I-25).
    One news source reported today that as many as 35,000 folks have been relocated. You can expect that hotel/motel vacancies will be non-existent in affected areas. And then there is the possibilty of road closures due to low visiblity and/or movment of emergency personnel/equipment.

    JimD got a reaction from adallak in New Battery Time   
    Lead acid battery technology is one of my hobby pursuits. And what I have learned may not be good news for retail battery consumers; it depends on how you view "capitalism".
    There are a limited number of battery manufacturers. They compete for contracts to supply batteries branded as Diehard or National or ACDelco or you-name-it label on the battery case. The battery manufacturer will run the same production line for Sears one week and ACDelco next week and the only difference will be the quality of the material contents according to the specifications of the contract with Sears or ACDelco or you-name-it label.
    Brand name allegiance is a risky game in a shrinking global economy. Cost-cutting is the retail corporate mantra today.
    Battery brand is not the yardstick. Decide how long you expect your battery to crank your engine and pay in advance.

    JimD got a reaction from Bruce Nunnally in Need Northstar advice   
    Enough is enough. Please lose the language and mindset of inserts or helicoils or studs or other unproven "fixes". Nothing need be done until there is evidence of head gasket failure. And headgasket failure is not unique to Northstar engines.
    GM/Cadillac and other car makers have been clamping aluminum heads to aluminum blocks using ferrous bolts for decades; they know how to do that. The physical/chemical challenge is how to avoid the predictable oxidation/corrosive action at the point where a ferrous bolt thread contacts an aluminum block thread. GM dealt with that in the Northstar by coating the head bolt threads AND designing the head gasket to keep the bolt hole in the dry.
    A head gasket can fail in such a way as to simply push combustion byproducts into the cooling system.
    Worst case is a head gasket fails in such a way as to allow coolant to come in contact with the head bolt threads. The coolant acts as an electrolyte and promotes/accelerates the predicatable oxidation.
    Reports of head bolt thread failures soon follow. But the reality is, the gasket failed.
    It would be folly to open the top end of a Northstar for any reason without properly dealing with the head bolt holes/threads in the block. GM/Cadillac Service Manuals specify TIMESERT products (http://www.timesert.com/) be used when clamping the engine back together.
    Anyone not prepared to assume the risk of a pricey repair with any vehicle at any time should buy new and trade when the bumper to bumper warranty expires.

    Folks, a 100 mile or a 1,000 trip is not going to yield accurate, reliable long term average MPG in the real world.
    For thirteen years of ownership (4,871 days), I recorded every drop of fluid and every dollar put into my dearly departed 1998 STS and let Excel do the math. I used the GAL FUEL USED display on the DIC and reset that display every time I filled the tank.
    Average MPG for 206,xxx miles = 21.6
    Maximum MPG for 206,xxx miles = 27.02

    Hey BodybyFisher, do you know why sealers do not work in a Northstar? I have already gone down the path of no return by using a sealer and I would like to inform the shop that did my work as to what happened and why. It may keep someone else from doing what I did.
    Advanced Auto has a product called Blue Magic and they clearly state that it works on Northstar engines. Best I could tell this is a Sodium Silicate product as is most other sealers. This is the one piece of information that gave me false hope.
    As you know a 11 year old Caddy has little trade in value and if I spent $2300 on it would not improve the trade in value. I gambled and lost.
    Do you have any suggestion as to what to do with a car in excellent condition that has a blown head gasket?
