  1. Well don't know if its a stupid question! But I've had my car for 6 months and the temp gage has always stayed at 12 o'clock. Latley I've noticed its started to move barley a 16th of an inch hotter an back, I've also noticed the upper radiator hose went from being solid hard to now I can actually squeeze it when its hot? IDK which is supposed to be right or if there's a problem or not. 2001 eldorado with 44 thousand miles, runs beautiful! Any Help

  2. 2001 eldorado, just got the " low refrigerant / a/c compressor off " message! I haven't been using the a/c because a noise in the blower motor when on High. But I wanna try and charge it to see what happens? Where do I start!

    Clear that code and see if it comes back.

    If it does not I would disregard it.

    Unhooking the battery will do nothing more than reset the clock and monitors.

    as for the cigar lighters  I wonder if one of them is bad and is drawing all the time but not enough to blow the fuse, then anything you plug in goes over and pops the fuse

    Could be! Gonna clear the codes to see what happens, if it comes back i will have to try the battery disconnect! Just got the car back,my daughter had to borrow it over night. So now I'm gonna first try a lighter from a different car an if it still blows the fuse I'm gonna take the front ashtray n lighter assembly out to try an trace wires to see if maybe there's a short somewhere. If I can't find it then I'm gonna take the back lighter  apart also, will see!!

  4. Actually have tried just the charger with the hood up an checked the fuse, it was OK. Then I'd go an plug the phone in and it wouldn't register a charge! So went back under the hood n the fuse would be blown. I'm gonna have to remove the ashtray door an try to pull out all the ashtray and lighter socket to see if I can trace it down if I wanna use it bad enough I guess. Hey thanks for all the response, I will definatley be talking with ya more. 

  5. Yes I did check both front and back sockets, nothing in neither one. An the fuse doesn't blow as soon as I put it in the fuse box. But as soon as I push the lighter in, either front or back one then the fuse goes! They've been that way since I've had the car. I finally just gave up on trying to use them. But it would be nice to figure it out, I would love to be able to at least charge my phone when I'm out driving.

  6. Ok good! Yeah I'm gonna check the PCM connection again first an if I can't come across anything I'll try disconnecting the battery! Then see what happens. Thanks. Hey also while I have someone that knows these Caddys, any ideas on both my cig lighters blowing out as soon as I try one. I've replaced fuses twice but can't seem to find the problem! I've checked to make sure there were no coins fallin in them that would cause a short. Its not that big of a deal but I would like to be able to charge my phone with either of them. Just thought I would ask.

    It was showing current at the time you ran the code check. Drivability may or may not show up depending upon what analog signal is causing the code. It is strange that the SES light did not illuminate.

    It is a PCM (powertrain control module) code but there are a lot of analog signals. Access the PCM again and make SURE all three cable connections are tight at the PCM. Check the wiring bundle and make sure there is no damage to the wiring.

    If you don't find the "smoking gun" remove both battery cables from the battery and touch the cable ends together (away from the battery) this will reset all the modules. Reconnect the battery and check the codes again with the engine running

    Hey I'm not sure if I responded back to you! It looked like I just answered my own post myself. I'm still new to all this forum stuff Sorry!! Did you see my respons?

    P-1627 is an analog to digital converter malfunction. It should have illuminated the SES lamp.

    The A/D converter takes the analog input readings and converts them to a digital signal that the PCM can understand.

    A faulty PCM, faulty or shorted wiring to the PCM, or a PCM connector not properly seated can cause the code. Have you had the PCM disconnected for any reason?

    The PCM is in the cold air intake near the air filter, the harness can get pinched and the wiring can be easily damaged.
