My buddy has an '84. When he took out the passenger side kick panel and the insulation pad he found a relay. I don't have one in my '85. Anybody know the function of this relay?

Had to post something to see if I figured out AVATAR

It's the power door lock relay.

Nice avatar.

My power locks only work to open not lock could this relay be the problem?

Well it could be a loose or broken wire (had one break on my pwr window switch...window went down not up on pass side only) could also be a switch is just old and not making good electrical contact...the switches can be taken out, and the back taken off to check. Could also be that the solenoid is worn out or is jammed because linkage is not moving freely or it is not making good electrical contact. Does it seem like the solenoid wants to pop up when you push the switch, and does it do it on both doors?

Well it does it on both doors they will unlock just not lock.. They do not even get a response to the lock try.

My power locks only work to open not lock could this relay be the problem?

It's a good possibility.

Do a quick test. Get a voltmeter and check for voltage at the relay. The blue wire is for "Lock". The black wire is for "Unlock". If you have 12V at the blue wire when you activate the "Lock" button then the relay is probably bad.
