Review on 🔌 Black Multi-Purpose Relay - ACDelco GM Original Equipment D1780C by Gene Rosado

As always, I have read reviews of previous purchases of this item. There were two reviews saying they replaced their two old relays with these and everything worked fine. The close and unlock relays are the same relay. I bought two of these and replaced my old relays with two new ones. The problem still wasn't fixed so I took my truck to the local GMC dealer and told them what the problem was and what I had done. The price I was quoted for replacing both door lock "actuators" in the doors was over $1,000! I decided to just replace the driver's side rear door actuator for $550 and my problem was solved! The mechanic said that "this" actuator is sticking and blows the fuse when triggered, after which none of them work. Surprisingly both rear doors in the cockpit open as they should with my door lock.
