Hello, looking over all the stuff from my car the circuits seem pretty straight forward. I would start at the fuse box and look over those. If those are good check your bulbs. IF all of that is good it could be the switch for the lights. the first click might be worn or lost contact to acknowledge the switch. Good luck, I know those shops are tough 75$ per hour and 1 hour just to look it over. hard to cough up right now.

Hi Doug, did you get any answers on your fumes? I am a new owner of a 1988 Lux and face the same problem, but only when windows are down. No problems with leaks to be found underneath or in engine bay. I wondered if there was some vortex at work dragging the air back into the cabin. It is spoiling the fun even though the weather is not great in UK at present. I am new to this site also, so I am sorry if I have missed any posted feedback. Mike

Hey t I have one more thing you might look at. I have been going through my car all over even tore the dash apart looking for a frayed wire or short. Looks like my problem was one of the big relays in the fuse box. I pulled out one G15 I believe. It is labeled instruments and light relay in the fuse box. Well the ends of it were blackened. i scraped them back down to shiney metal and plugged it back in. My brake lights and dash came back to life. So i would check some of those they may just be dirty and not have a clean connection.

Battery not charging

Heres my problem. I've got a 1984 944 w/ a new battery and rebuilt alternator. Everything was running good and all the sudden the battery will not charge. i've tested the alternator and it is good. I tested the ignition wire ( wire that goes from ignition to alternator) with the key in the on position and it is not giving any power out. is this my problem?

Hey thanks again for replying . I figured it out it was a bad connection from one tail light to the other. i ran a new wire and viola all my lights work.

tdouble, not sure on the ignition wire. I would check your batter cables though. Just because they look good on one end or the other. the cable could be full of corrosion under the shrinkwrap. This could stop the flow of juice back to your battery. Just cut into a section behind your cable where it is shrink wrapped. Open up the shrink wrap and look at cable. The cable should be shiney, if its is full of green or brown crud then i would say just buy a new cable. If cable looks good then just get some electrical tape and wrap the cut section back up.

Hi Doug, Hi msim.
I'm led to believe that when you open a window or sun roof in the 944, it creates a differential pressure in the cabin. This tries to 'suck' hot engine air (not exhaust) in through the gear lever housing and gaiter. With a good seal on the gaiter, no fumes but a lot of heat. With any gaps, engine air gets in and smells. How dumb - open windows and it gets too hot.
Haven't heard of a fix but I would havr thought that some sort of heat deflector could be rigged up under the gear lever ???

924S Fuel Pump Problem
by pdunk2009

I'm replacing the fuel pump and even though the new battery has 12.6 volts there is only 9.8 volts at the pump terminals with the pump hooked up. And it will not run and pump fuel. Out of the car the pump runs fine using a battery charger or battery and there is 12.6 volts at the pump terminals. If I'm losing voltage through the pump relay is there anyway to test the relay to see it it's the problem?

Honestly, they go bad quite frequently. It's the DME relay in the fuse panel.
The only way to really test it is to take it out and use a continuity voltage tester on it by providing switched power and a continuous hot and then just measure the voltage going into it and out of it.
