Power Door Lock Question

I had the same problem with both doors when I bought my 88 RC. It had been sitting outside and not used for 2 years. I couldn't unlock the vehicle to get in without using a technique that I learned during my misspent youth . It turned out that both of the door lock solenoids were seized up. In this case, I was able to just keep working the PDL switch back and forth while pulling up on the lock knob. Took a while, but got both of them working and I haven’t had any trouble with them since. If your problem is with the solenoids and they have been this way for a long time, you will probably have to pop the door panels off and try and get some penetrating oil into the solenoids. If the bottoms of your doors are rusted and salt has found it’s way inside the door, then you may have to disconnect or replace the solenoids.
