tail lights/ relays

[brnstorm]

I have an 87 944 that has been converted to a CAB. I am having a dickens of a time sorting out the marker/tail lights. The left side works swell. The right side went out. No front marker, no rear, no tail light. The signal lights work F & R. The brake lights work ( until the water that they accumulate cracks them!) I have had them working twice since owning the car. I bought it a year ago. It has 47,000 now, had 40,000 a year ago. It was built by a body shop in 92, who then kept it for 16 years and added only 1,600 miles. When I bought it everything worked. When I went to drive it home almost no lights worked in the back. On the way home, they all came back. They worked for about 6 months, then I started having starter trouble, then, apparent on the gauge, heating trouble. A new Starter didn't help, but I reasoned that it was a bad ground. a new cable, battery to engine block, fixed the starter as well as the gauge problem. But now the tail lights didn't work on the right, the front and side marker light also were OOS. I tried wiring from the license plate light to the tail light and rear side marker, and that worked. When I tried to wire to the front markers, I got a spark, and it seemed to reset some relay, and suddenly the fronts work and the rears also worked when I rewired them as original. That lasted about two weeks.

Can any one relate to this from prior experience? Can anyone tell me which relay might be causing this? I checked all fuses, and cleaned contacts on all relays. No help.

If the '87 still uses ceramic fuses it wise to replace them. They might look fine but develop corrosion at their ends andcause loads of intermittent problems.

I don't believe it does. It has the plastic staple sort of horseshoe affair. not barrel shaped like my old VW

Still, you should check all of the fuses, on the older porsches they use a fuse for the left lights and one for the right. I had the same problem on my '77 924. As soon as I replaced the fuse and cleaned up the fuse panel I haven't had a problem since.

Good Luck!!
