Your 1994 jeep grand Cherokee keeps blowing the 20 amp power relay fuse when you try to open the doors using your key less remote any idea why and where would the p lock relay be located?

Answer 1

The power lock relay is located under the dash to the right hand side of the steering column. There are actually 2 relays. A power lock "lock" relay and a power lock "unlock" relay. The relays are all the way to the right of the relay center (one over the other). I have the same problem. My 1994 started locking spontaneously. I made the mistake of leaving it running and locked myself out. Fortunately, I had a spare in the house. Anyhow, I pulled the switches out of the doors and swapped them without any changes. I started blowing fuses as well. The power locks would lock the door and I could not use the switch or the key fob to open them. I had to manually unlock them. If your doors spontaneously lock, change the power lock "lock" relay. Most likely it is the cause of the problem. The relay is sticking and drawing power until the fuse blows. I hope this helps your problem.
