ok, I have an 88 hatch with a clock off a 90 91 model dont know what year. but I plugged it in and it doesnt light up. if you press the buttons it lights up but other than that it doesnt. friend said it was probably because im using the 88 89 dimmer switch, anyone else have an opinion on it?

 

i have an 89 with 90 91 clock, i just plugged mine up. it doesnt light up when the car isnt running (of course), it turns on when the car is on and dims when you turn on your lights...maybe its the clock?

 

thats strange. the clock works just fine it did right before i unplugged it from the other car.

 

Check your number... 17? I think fuse. Its labeled as clock in the panel anyway. When mine was blown the clock would light up dim, and come on when you pressed the buttons to set it.
