Last week I replaced the outer window sweeps on my car, All went well. Now I just put the car back in the garage for the week and I want to try to fix the INFL REST light. I think I read on a post that you have to clean a sensor and put grease on it. Does anybody have a picture of the location of the sensor, and refresh my memory if I'm correct in the repair.

Must be a 90. The driver side one is on the frame right behind the battery box. It has a yellow cable coming off of it with 2 arrows pointing forward. A 13 and. 10 mm head bolt in it. Passenger side one looks the same and is right under the heater blower motor. Its easier to get to if you remove the lower fairing piece and loosen the window washer tank. The driver one is easier to get to if you remove the battery tray.

I had that light on in my '90 as well. I took the sensors off and cleaned then with QC Electrical Connector Cleaner and used some di-electric grease in them when I put them back on. The lights went out for a few weeks but came back on. In my case it was just bad sensors. I ended up stripping the car and making a track car out of it so I didn't replace them.
