Hey I recently added the permanent fix relay upgrade to my 62 for the windows and the doors. With the locks it worked great then I lost the rear passenger locks both sides but the front locks still worked. When you put your hand on the lock and hit the switch you can feel it jumping. I had all four windows rolling up with speed then lost the rear drivers side door. I wired another relay and that did not fix the window I checked it with a regular switch no relay and it did not fix it either. I have good grounds to the chassis on everything. Any thoughts? Very impressed with this fix for slow windows and locks.
