I had enough of my power door locks not working, so I took the door panel off and checked the power door lock control unit. After a few tests of the wire harness plug, the control unit is bad. Looking at the control unit pcb, it looks one solder joint of a relay is worn out. Could this be the cause, because the unit costs about $150.

Anyone else fixed theirs be resoldering the pcb?

The contol unit is for sure bad, because I got the all the door locks to lock and unlock by following the troubleshooting guide from the online manual at:

this happened to mine also. i resoldered the pin back on and it works perfectly
