Power Door Lock issue
« on: November 18, 2017, 16:35:16 »

I just picked up a clean 87 fifth avenue and the power Door locks will unlock but not lock. I disassembled all four doors and cleaned and lubricated all four latch assemblies. Neither Door switch works and the solenoids don't make any noise when trying to lock the doors. After cleaning all four unlock nicely. Any help would be appreciated. Thanks. murf

Check the switches. One bad will make both not work.
tHe wiring between the door and body is also prone to breaking but the way the locks work is it reverses ground and power so if that was a problem they shouldnt' work at all. Unless someone has done something strange with the wiring in the last 30 years.
