Thanks for the info. I don't believe a phone call will be needed. This is almost as bad as changing the alternator on a 2012 Buick Enclave which I had to do three months ago.

HI,

Yeah, not fun on this one.

Just for future reference, 99% of the time a phone call is just a waste of your money as I can handle just about everything online this way. The phone request you see pop up is automated that the experts have no control over to turn off.
