Anyone know where the door lock relays in a 1985 S-10 Blazer are?
The locks never worked since I got it and I replaced the carpet and front seats this weekend and was going to fix the locks to, couldn't find the relays.

 

start with looking under the hood crazy spot but start there if not there look inside the cab driver side or under the dash passenger side.

 

Been under the dash both sides. Never thought about under the hood....

 

Call me crazy, but I don't see any relays in the power lock diagrams I was able to dig up in my references...

Do you have power windows as well?

 

Yep -power windows, door locks, cruse control, power back glass release. I'm uptown. Only problem is the only lock that works is the passengerside unlock. I've been all over the insides and can't find the frickin relays.
I had all the seats, panels and carpet out of it a few weekes ago. Put dynamat everywhere so I had a good look around. Put in seats from a 2001 blazer, electric, lumbar and heater...nice!

You think this is a no relay system???

 

The wiring diagrams I was able to find in my references said nothing of relays.

 

Can you scan that and send me a copy. How are they reversing power to the lock motors from 2 switch without relays. Don't you find that odd. I didn't pull a lock motor out is there 3 wires going to the motors?

 

I'll see what I can do. A double pole, double throw switch would reverse the power just the same. A lot of the older stuff is setup this way.

I won't be able to get to anything tonight so hopefully it can wait until tomorrow afternoon...

 

The locks never worked since I got it, I think I can wait 1 more day...if you hurry :-)

 

Here ya go:


Sure looks like everything is handled at the switch.
