Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello. My name is ***** ***** I will be helping you today.
I dont have a whole lot to offer with what you are giving me to work with but I would bet either a wire was damaged or connector left unplugged when the thermostat was done. Check over all the wiring near the thermostat with a fine tooth comb. If that doesnt help youre gonna need to find a way to get the codes. I can make some suggestions if you want.. just let me know.
You need a scan tool.
