Congratulations! And THANKS for saving another fine Imperial. :o)Dear Imperialists: Saved another one from the derby demons. Owner had two offers to destroy this one!
Just replace the whole switch. The same seat switch was used for several years on a BUNCH of different Mopar products, so finding one should be relatively easy.2) The middle power seat button is missing (forward/back), can I replace just the button or does the whole seat switch need to go?
You got it. If you can hear the hiss and the pedal is stiff, the diaphram inside the booster has torn. These can be rebuilt, and I think you can buy a replacement at NAPA or other stores. The last time one went bad on me, I was coming down an exit ramp at 75+ mph. Nice little surprise at that very moment!3) Brake booster was replaced by a shop and bled, but no power boost now. Hissing when pedal pressed hard. Stopping is a leg workout. Bad booster?
It can take a while to sort out the AutoTemp system, but it CAN be done. You'll want a shop manual for sure, but also take a look at the AutoTemp Diagnosis and Testing manual at http://www.imperialclub.com/Repair/Lit/Master/245/index.htm4) Autotemp blows only hot (like full heat on) air, no matter what the temperature dial is set at. OOHH how I wish this had manual air (and both floor vents).
