Hey, Scotty
just recently my trailblazer started idling funky, but only when the heater is on. No codes pulled up on the scan tool, what would you suspect

do the lights dim at the same time?
Yes, I placed a new battery to see if that corrects the problem and it didn’t
the battery only starts the engine. The alternator is what powers everything.
Yeah, possibly a bad alternator. Had a Beretta that would die when I turned on the headlights and air at the same time lol, was the alternator.
