1 way pwr. doorlocks

[strkpr]

My 85 power doorlocks wont lock the doors, but it will unlock them. Ya its only 2 doors but I would like them to work.

If neither PDL switch will lock the doors you either have a bad Door Lock Relay, or you have two sets of dirty switch contacts on both Door Lock Switches. The Door Lock Switches energize the Door Lock Relay which controls the voltage polarity going to the Door Lock Motors. I'd suggest checking the switches first. You can probably get them out of the door panel without taking the panel off. Unplug them and take them apart. Clean and re-adjust the contacts and try them again.

Here is a schematic of the Door Lock Circuit

Yes, but they're great if you want to change your eye color to green!
