    I have issues - 1994 Deville 4.9

    We went and bought a 1994 Deville 4.9 - 130,000 mi
    It has NINETY SPECIAL By E&G on a badge; i think that just refers to the "Landau" vinyl top treatment.
    There are no codes and it runs and drives great.

    Anyway as normal it has a few issues. I searched but found nothing really.
    Here are a couple of my head scratches.

    > Right rear window taped up.
    Any known common problems here?

    > The outside temperature gauge reads about 120 degrees.
    So it is leaving the vent open (It was a cold ride home).
    Where would a person start looking?

    Thanks

    Outside temp sensor usually in front of radiator. Unplug and see what happens.

    Re: I have issues

    It's probably bad then. Not uncommon for them to fail. At least vent should stay closed hopefully until you get another one.

    Re: I have issues

    Ok
    The service manual has nothing much to say about it ether.
    Just that it exists and its information is added to certain calculations.

    I will go out here and get one off the parts mobile and let you know what happens.
    Thanks

    Re: I have issues

    Well you got that one.
    Swapped the sensor out with one off our parts mobile and it seems to be functioning again - That was easy.

    > No known common problems with the rear window?

    > Going out to try and fix the drivers door lock - the power actuator seems jacked (but now the key will not work it).

    > Where is the first place to look if the dash switches (Gas door release and trunk release) fail to function?

    Re: I have issues

    Look at valet switch in glove box if gas and trunk switches don't work.
    No common window issues I have seen on those years. Only issue may be window switch bad, but who knows until you get it apart.

    thanks

    Not the valet switch.

    Good to know on the windows.
    Maybe it will be something simple.

    Had a go at the drivers door - power door lock actuator - today.
    I got it working but it is weak pushing.
    Looks like it will be tons of fun to replace.

    Power door lock actuator
    I have searched everywhere and i can not get a good idea of how hard this task will be.
    Anyone been in there can give me some insight - tips?

    If the weather is good i may get to that rear window today.

    Got the passenger side rear window fixed today.
    It was just the motor.
    Even pulling another motor off the partsmobile it was still quick and easy.
    Probably easier than there tape job. Did not take long with a razor blade to clear the tape residue.

    Still not informed enough to tackle that Power door lock actuator.
    No one has been there before?
    To hard to explain?
    The service manual does not really say much about the procedure.

    The repair list is getting shorter.

    Re: I have issues

    It's buried for sure. You might try lubing the bushing before tearing it out, those little plastic connectors can wear and start sticking.

    Got some remote fobs programmed to the vehicle.
    The trunk release works with the fob.
    Nothing from the dash switch - These service manuals are stubborn to get info out of.
    The fuel door release is all jacked up; looks like i will be replacing most all of those parts in the trunk.

    Picked up some silicone lube - i will have another go at that driver’s door lock actuator.
    The manual finally revealed there belief that the door must be gutted to replace the actuator.
    While i am in there cleaning and lubing i will see what else i can see

    Re: I have issues

    Next problem
    Having trouble figuring out what all these radiator lines and coolers are.
    Also having trouble getting pictures up
    Lets see i can type you into it.

    Radiator has 6 connections with two coolers out front
    1> Passenger side = upper and lower hard lines - Look like transmission lines to me - lower radiator hose

    2> Front of radiator coolers on drivers side they are stacked out -
    radiator then what looks like a trans cooler - then what looks like a power steering cooler

    3> My problem area - Drivers side - upper radiator hose
    upper and lower lines that look like power steering pressure lines.
    The lower line is leaking bad onto the ABS unit.
    What is leaking looks like engine oil.

    I can not fix it if i am unable to name it.

    Thanks

    Re: I have issues

    Bump
    I do not think the name of the post is conducive to getting help?
    But i thought i could keep most of the isues with this vehicle in one place.

    The Service manual is very difficult to extract knowlege from.
    It say it could be a oil sending pipe (well Duh) - maybe trans axle oil cooler

    Thanks

    Re: I have issues

    Found them
    They are engine oil cooler lines.
    I did not take the air filter box off; so it made it hard to see they go to the oil filter housing.
    After i figured out what they are supposed to be and looked at it again i can pretty much figure where they are going.
    So the lower one is inlet and the upper one is outlet
    About 100.00 for the pair.

    Thanks
