Hello All, I have a 2007 Tahoe with a no assist rear hatch. My problem is that the hatch will not lock or unlock. The 4-doors and the hatch glass work as they should. I've checked all the fuses and the relays and all check out ok. I did order a new BCM ( Body control module ) because we were having a issue with the gauge cluster stating hatch was open when it wasn't. Now I have a issue with the lock working, so I returned for repair (Programming). After having the vehicle totally de-commisoned for a month. I'm frustrated. Is there a way to test ? I still feel the BCM is the issue. Any suggestions ????
