I have an 89 firebird formula, I cant figure out why im not getting power at the headlight motors. I changed the headlight module and still no power, the motors definetly work (I hot wired them). Each headlight motor has a 2 wire plug. IS THERE ANY FUSES THAT GO TO THE MOTORS. any ideas will greatly appreciated.

 

Check your 'tail' fuse and also check for power on the 2 red wires at the module. They should both have constant power... helpful drawing

 

There are two fusible links, blue in color, inside the wiring loom about 6 or 8 inches from the module.

 

I have power going threw the module and the fuseable links are good but still no power at the motors. Is there any groundsthat i check.

 

anyone

 

Yes, there is a ground on the actuator relays. They are at pin "C" on connector C1 of each one. There is also two fusible links in the circuit with one going to pin "A" of connector C1 on each actuator relay. They should have red/white wires.

 

Check both wires going to the motor to ground, you should be getting 12V (more or less) on each wire. The module switches ground from one wire to the other depending on if up or down is being selected. If you have 12V on both wires, then remove your headlight switch and clean the contacts on it and the harness end and try again.

This is based on the 91 firebird headlight wiring, not sure when it changed from the individual relays to the module, but if it has the control module on the firewall it should work the same.
