2002 Suburban Power Locks Not Working
Bought a 2002 suburban 1500 lt 4x4 about 6 months ago and it has been great. Unfortunately, about a week ago we were out running errands and the power locks just stopped working. They no longer lock/unlock automatically when you start driving or place the vehicle in park. We have 2 FOB's that I just programmed about 2 weeks ago. So far I have replaced all fuses/relays in the fuse box and under the hood. I removed the drivers side switch module and cleaned everything I could but I wasn't sure how to test that switch. I have also tried to look around for any loose or pinched wires but I haven't seen anything.
Other symptoms: noticed that I only hear the relay click when I press unlock from any switch (drivers side, passenger, lift gate, or FOB) but I don't hear anything when I press lock from any switch. Also, I played around with the relays in the fuse box and noticed that when I remove the drivers side lock the unlock button will partially work. I also noticed that the relay for the drivers side lock is warm to the touch, while none of the others are warm at all. Could that be a problem?
Any suggestions?
Thanks!

Welcome to the forum. Since your first problem started noticing your statement,
They no longer lock/unlock automatically when you start driving or place the vehicle in park.
I believe I would look for some type of switch located on the steering column, since the gear shifting controls locking/unlocking the locks. JMHO and good luck.
