Getting a check engine light, reads U1510, no K code.
Tuner is reading it as "faulty HVAC control module".
Anyone dealt with this before?
Have searched the forum with no luck on this particular K code. They all refer to other K codes under U1510 and suggesting to remove connectors, clean them, maybe add dielectric grease, and reseat. Well, obviously this one isn't going to be easy to get to. They also suggest removing the negative battery cable for quite some time then try again. Tried that, didn't help. Odd thing with this CEL is it only comes on if I try to remote start my truck. Went a week with manually starting with the key, no CEL. As soon as I try remote start, throws a CEL and won't remote start. Otherwise, truck runs fine with no other issue.
EDIT: Wanted to add that I have no issues with my HVAC, air is cold with A/C and heat is hot when cranked up. Only noticeable issue is changing fan speed seems to have a delay now, 2-4 seconds before fans ramp up or slow down. Related? I don't know.
Is this control module in the dash? I hope not. I hate dash work.
Don't think I want to go to stealership yet. Read a lot of talk about them not having a generic starting point with U1510 due to complexity of K codes so usually ends up being a 3-5 day ordeal. Not interested.
