my driver side window stop working on my 89rx7 vert . I cant find where it is in the FSM . the passenger side is working from the driver side switch . how can I check the driver side regulator and switch

 

The diagram is in the electrical section in "K-1." To make the window go up the Red/Black wire receives voltage while the Green/Black wire is the ground wire. To make the driver window go down the R/B wire is the ground and the G/B wire is the voltage wire. Chances are your switch is dirty or damaged.

 

Or you have a failed window regulator.

 

I got some electrical contact cleaner and sprayed it while jamming on the button and problem solved.

 

Not solved, just temporarily abated.

Solving the issue will require relaying the circuit and taking apart the switch to clean the contacts more thoroughly.
You bought some time, that's all.

 

^that, look up window switch rewire, it involves relays, and it helps... ALOT

 

I opened every section of 1989FSM on foxed.ca and found no section K-1 Have I got the wrong FSM

 

That's the same site I use. There is an electrical FSM for 1991 (S5). Its located about 3/4's the way down the document in section K-1.

 

thanks I found the electrical FSM I also found in the regular FSM under body section S a complete breakdown of the door panel and check of the switch for anyone who might need help finding it

 

I did the relay install for the passenger side based on this writeup. .

We had to disassemble both switches to clean them out as they were both heavily carboned. The ABS plastic socket that holds lever arm in the passenger switch was broken so i used dynaweld epoxy to fix it. If this socket is broken the window wont go up.

The relays were easy to attach to the door using M4/.7 x 20mm machine screws and washers into existing blind nuts. Here is a picture before I wrapped the wires.
