Great info on the Sun Roof repair which I did last November whilst I had it in pieces I also replaced the sunroof inner lining as it was torn and used Super Glue to make sure the corners do not curl up again.
I have just encounted the battery flattening curse after I parked the car up over xmas and now after charging the battery I cannot get the motor to start turns over but no firing of cylinders does any one have a checklist to follow abnd track down the reason for dead motor. Could this be due to Battery about to die as its been flattened right down twicw in the past three months? I am going to get a new battery to give me a good power source before I try to fire the motor again. any assistance would be appreciated . relays to test fuses to test and replace and a checklist to follow to cut out wasted effort and more flat batteries.

pop up lights not going up or down for early 928's
If all other tests for relays, fuses, and light switch have been performed and headlamps still don't go up or down or both, then I would recommend removal of headlamp motor by removing (3) 10MM bolts and (1) 10mm nut just left of driver's side headlight under hood. Prior to removal, take photo of (4) terminals to headlamp motor. Once removed from car, carefully peel back rubber boot from motor. It will most likely reveal (2) diodes which are faulty. Buy new diodes from radio shack. Unsolder old ones and note location of white band on old diodes and resolder new ones in same direction and location.
P.S. make sure to hold the headlamp from crashing down to it's sockets prior to removal of 10 mm nut from headlight motor shaft. Also prior to reinstalling, test by grounding the headlight motor housing, reconnect (4) wire terminals to headlight motor housing in correct order, and turn ignition switch to on( don't start car), then turn on headlight switch. You should hear and or see motor shaft spinning and stop. Now switch ignition off, remove terminals from battery. Reinstall headlight motor. This takes some practice. I hope I helped some people, cause it worked for me. |
can anybody help me with opening this list? #32 in particular

I think I will end up removing the seats. Besides, I might find some money or contraband (As I have yet to remove my rear seats in this car and I fear what may be lurking under them...)

Nice. Where did you get the blue part?

Hi,

'88 928, replacing the center vent handle (above heater/HVAC controls) the lever has to go thru bracket on the right and put the lever hole on the pin guide
where is the screw or ? that holds the bracket in place. Do you have to remove the glove box? |
Sounds like you've already done some solid work on the sunroof, nice job sorting out the inner lining too.
Now, about the non-starting issue after the battery went flat, you're definitely on the right track by planning to replace the battery first. A weak or deeply discharged battery can cause all kinds of strange behavior, even if it *seems* to crank the engine fine. Low voltage can mess with the ECU, fuel pump, ignition, and sensors. |
