I think my ABS light is burned out. It doesn't come on when the key is turned on before starting the car. Anyway, I got an ABS module from the junk yard, put it in, and now everything is working fine, at least for the past couple of days. We'll see if that continues. Thanks a lot for everyones' input.

The ABS and Trac lights are not on. The ignition switch is new.

Just got the car for my son. Odomter didn't work, so I replaced the broken gear. Now the speedometer and odometer work intermittently for a short time, then stop. I have heard this might be an ABS module problem, but any other suggestions?
Thanks

I had the upstream sensors replaced. Still has the same codes. I'll try the smoke test.

Thanks.

Hesitates on acceleration. It has aftermarket plugs and a few aftermarket coils. No evident vacuum le...

Sorry. The fuse was actually bad. They work now.

2000 s80. Looks like it had fog lights before. It has the wiring, attachment plug, and the dash switch turns green when pushed. I put in new fog lights, but they won't light. No power to the attachment plug. Fuse is OK. Could the relay be at fault? If so, where is it located and how is it tested? Th...

The dealer says that the driver's side door lock latch was loose causing the door not to lock, which somehow affected the sunroof and lights. Reconnecting the door latch to the door lock assembly fixed the problem .
