"Panel Dimming Switch Pot Circuit"<------------whats that and how can i fix it?

and how come the low fuel message is popping up now. i never saw it before and i've been on low fuel plenty of times. back to the a/c:

so if i was low on refrigerant than i would get a code for it?

Panel Dimming Switch Pot Circuit is the instrument panel dimmer switch (POTentimeter).

Are you actually low on fuel? That is the reason for the message. To get your attention and get you to look at the gauge.

Yes, a low refrigerant condition should set a DTC.

can the a/c accumulator/ aka drier, and condenser, or even evaporator be factors as to why my a/c wont blow cold or my heater wont blow warm. what do i check on each part to be sure of how to diagnose the problem

Hi

I think you should take the car to a reputable AC shop. There are just to many unknown factors here, for anybody to troubleshoot this one for you.

Good luck and let us know how you made out.

I Guess so.i have no choice

[kjelie8706]

so i have great news. i'm a step forward now. i went digging for the fuses under the hood, and there were a few hidden ones in a enclosure, i swapped out a few of the fuses and presto my compressor actually does work. and it seems the system is actually holding it's pressure. but still no cold air. i took a look and the condenser and theres really no debris, only a few pebbles here and there. but can the condenser still be a problem? i need cold air.

[Ranger]

So you had a blown fuse? Have you put a set of gauges on it to see what your pressures are? Are the pipes cold?

[kjelie8706]

i need to buy a real gauge that'll actually tell me the pressure rather than say, EMPTY, FULL, WARNING, OVER. the pipes? one pipe from the accumulator was cold while the other was a bit warm, but no cold air.

[kens96]

Sounds like swapping the fuses was the same as disconnecting the battery. Are you sure you did not have an AC code for low refrigerant? Disconnecting the battery or pulling a fuse will reset the Code for this.

nope, no code. i even discharged the system and no code either. but today i got a new code.

Why on earth would you let the refrigerant out of the system????

Please, before you injure yourself or someone else, take the car to a competent A/C shop and have them look at the system. It is blatently obvious that you have no clue what you're doing and you are going to cause more issues than what is likely wrong with the system in the first place...

Federal law prohibits the venting of refrigerants to the atmosphere... and the fines are very severe

[BodybyFisher]

I am glad it wasn't just me thinking this, I have said the same earlier in this thread.

NOW, not only do you need someone to repair the system, you need a FULL RECHARGE. My guess is that with the cost of freon, the FULL RECHARGE ALONE will cost about $175.

This is not personal, AC requires SPECIFIC knowledge, experience and equipment. The air handling system is confusing at best. It took ME, 2 years to figure out why I was loosing air flow from my vents on acceleration and I have a list of auto mechanical experience that would knock you over since I was SIX years old hanging over the fender of a 49 Mercury standing on a milk box.

I recently took my car to have it charged in Pennsylvania as I lost my AC on a trip. The old timer mechanic who was sharp said he had NO experience with Cadillac AC systems they are complex! I myself neglected to check the codes thinking that my AC system was LOW on freon. It was an air mix servo that was bad and I wasted $100 and 3 hours while I was on vacation because I was too stupid to check the codes.

The problem is that you are doing things and asking questions that make it obvious you are not capable of fixing this. Again its not personal, if you do a little research, you will find that I myself and others will stay with a member for WEEKS helping them diagnose their problem. Because of the responses we are getting from you, not only you, but we are wasting our time. In Florida, AC repair shops are as common as fast food joints, find a good one. We NEVER tell a member to take it to a shop, but in this case it's necessary.

ok i understand what you're saying, but i cant afford that. thats why i've been trying to become mechanically inclined, i just kept buying cans of refrigerant, isnt that all i have to do to charge the system. and i the system isnt totally empty. the reason i did it was because the last two can of didnt even make the pipes cold. so i thought just to discharge it so i can add better refridgerant. i cant help that wanna do it myself.

OK, I understand. The problem is this, at some point the system requires an evacuate, meaning that the mechanic attaches a vacuum pump and they suck a vacuum for 30 to 45 minutes (KHE correct me if I am wrong with the time), they do this to draw out all of the freon AND moisture. Because their is a vacuum the freon easily flows back into the system and they measure exactly how much freon they put in. Putting too much freon in is no good either. KHE could you explain what happens when TOO much freon is in the system?

If I were you, I would have it evacuated and recharged as long as the compressor runs.

[Burcham]

Sir or Madam, whichever the case is. After reviewing all 50 or so of your posts. I think I may have the answer to your ac/heater problem. On 01/31/08 under the ENGINE COOLING Forum you made the following post.

ok for one it doesnt blow hot or old. what should i do. i added refrigerant but no effect. also the a/c seems to only blow from the defogger vent not the passenger and drivers vent as usual. i hit the buttons to change it but nothing works now. is there some thing i can check. i need my ac to work. AND ANOTHER QUESTION. MY 1992 STS SEEMS TO BE DIFFERENT FROM OTHERS. THE CONSOLE IN FRONT MIDDLE SEEMS TO BE UNIQUE. IT HAS THE RADIO CONTROLS AND A AC CONTROL CONSOLE. BUT MY CONSOLE DOESNT WORK. I PULLED IT OUT AND I COULDNT FIND THE HARNESS THAT IT CONNECTS TO EITHER. AS IF IT DOESNT EXIST EVER. CAN ANYONE SEND PICTURE OF THERE STS CONSOLE AND MAYBE WHERE I CAN GET A REPLACEMENT. IF ANYONE READS THIS AND THIS CONSOLE SOUND REMEMBER. HELP A FELLOW CADI OWNER OUT. HOW MANY FUSE BOXES DOES IT HAVE

As a certified GM technician specializing in AC systems I will try to help you with your problem, but the proceedure must be followed exactly or you could damage a lot of expensive parts and possibly ruin your engine.

The Procedures.

1. Get 2 gallons of gasoline in a sutiable container and pour it into the gas tank through the gas inlet port on the side of your car.

2. Put the key in the ignition turn the key to "Accessory" and turn the AC/Heater off.

3. Start the engine. Did this turn off the check gas gauge? If not go to the nearest station and put in a full tank of fuel. Did this turn off the message? If not you have a separate problem with the sending unit on the gas tank, ignore it for now.

4. Shut off the engine, check the motor oil level via the oil dip stick on the engine. If low, fill it to the correct mark.

5. With the engine cool check the radiator coolant level, if low add coolant.

6. Check with a tire pressure gauge, the air pressure in all four tires, and the spare, add or remove air as specified on the label on the drivers side door.

7. Return home. Look in the phone book yellow pages for a vocational/Technical school near you.

8. Call them, and ask if they have a auto mechanics class, and when it meets.

9. Go to the class, and ask the teacher if its too late to enroll and if so may you sit in on the class.

10. Explain to the teacher your problem, and ask him to give you any information on the problems you are having.

11. Buy a FSM (Factory Service Manual) and turn to the section on A/C Heating, Please read the part at the first of the section about not preforming any work on the system unless qualified.

12. If the instructor cannot help you, take your car to a qualified AC technician because although I have never heard of anyone getting killed while working on an automobile AC system, there is always a first time for everything, and I think your chances for being first are above average.

Please remember this is in jest. I'm not trying to put you down, but sometimes you can tear up a lot of expensive stuff trying to fix something you don't know anything about, believe me, I have been there and done that and got the tee shirt. Dont get discouraged, stay on the board and keep asking questions, but in reality, if you really do want to become mechanically proficent, you do need a little instruction from a person in real life. I have done a little mechanic work in my life, but what I know would'nt make most of the people on here blink. They have helped me several times and are great people. Please take heed of their advise.

Sincerly

If I were you, I would have it evacuated and recharged as long as the compressor runs.

The first thing a shop will do is recover the existing refrigerant out of the system with a recovery/recycling machine. The machine will recycle the refrigerant to remove imputities (air, moisture, etc.). Then the recovery/recycling machine is set to evacuate which draws down a vacuum on the system. After 30-45 minutes, the proper amount of refrigerant is charged into the system (by weight) that is under vacuum.

Overcharging will place strain on components of the system and the system will cool poorly. Too much refrigerant can also cause the high pressure safety valve on the back of the compressor to open so the system does not burst a hose.
