Power locks WONT LOCK but WILL UNLOCK

[Bdoza88]

I have a 84 cutlass supreme and my power locks will only unlock but wont lock. I have all new switches and checked all wires and connections. Any help would be appreciated. Thanx

sounds like the relay is defective...

I would also check the contacts on the switch itself many times they are corroded and just need a little cleaning to function properly.

I just checked switches and all connections are fine. So its probably the relay I removed and now cant find anywhere that sells it. I checked autozone, discount auto, napa, and the gm dealership and nobody has it. Anybody know where I could find one for sale or how I could wire up to a different 5 pin relay?

You said you "checked the switches" did you take the back cover off the switches and check the copper contacts?

 

[Bdoza88]

yea and I also bought new switches to make sure that wasn't the problem

Did you check the relay with an ohm meter?

 

[Bdoza88]

no I haven't checked the relay with an ohm meter

I found the relay on ebay for $130. that's a little more than I want to spend on a relay. does anyone know how to wire up a new 5 pin relay? they have them at autozone for $15

Check with your local car stereo shop. If they do alarms, you can convert to a conventional Bosch 5 pin set up. There is a dual socket available to eliminate the funky factory one.

To wire up just the lock side on a 5 pin Bosch style:
86= Lt. blue lock wire from switch
85= ground
87= 12v
87a= ground
30= lt. blue to actuator
