Power Window Problem 94 Full Size Blazer

[66chevelle]

I am having a problem with a drivers side power window, 94 full size blazer. After replacing the motor sometimes the window will not function (as if no power), lights do not dim, regulator is fine. There are 2 relays in the door mounted on a bracket. What is their function and are they known for failure? Thanks

Maybe next time I will have a more interseting topic.

 

I repaired it myself. Those relays inside the door operate the power window motors. One for the drivers side one for the passenger side. These must be checked before replacing a motor. On this vehicle it was either the relay or the spade connections on the connector. I replaced the relay to be safe.

 

Your welcome.
