Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
The PCB relay is Printed Circuit Board so it is integral to the fuse block.
So if it is defective you have to change the entire fuse block?
the relay can click and not send power to the fuse, that would be bad contacts but then you should have been able to make the hatch unlock if you put power to that fuse unless there are 2 issues .
Yesterday you mentioned using a scan tool in the diagnostic section. What kind of scan tool are you referring to- something like a Snap On or OTC quality?
yes, snap on solus, GM tech 2, OTc Genysis
I dont own such an animal, just a goodmultimeter, will this work?
No, because it is a module, we need that sort of ability.
So you say now that putting power to the fuse did make it unlatch.
This does point even more to the fuse block
They are bad for problems in these vehicles .
So I have heard, among other problems with this vehicle, the steering module failed last year along with the tailgate glass wiper motor. As well traction control glitches that were covered under warranty. I think we have suv from hell.
Wonder if it would meed the lemon law in your area?
Transport Canada has some regs. concerning safey related issues, not sure if there is an actual lemon law though.
Your in CAnada, OK, I know some states have them.
I would call GM and ask about some goodwill warranty on this
Powering #4 fuse term. did not unlatch the gate, Correcting my response above.
Are you still responding?
MY last reply did not come through then.
I was saying that this may be a cause and result. A short in the wiring may have caused the contacts to fail and also stops the actuator from working
Did you happen to get a chance to check the wiring in the boot from the body to the hatch?
No not as yet, my daughter is wanting her SUV back . Will have to continue with this problem at a later date.
OK, reply as you need, we can take as long as needed!!
