AC and ECU blower issues

[steve-jarvis]

Hi

Grantuismo 4.2

I’ve recently had the heater blower motor and ECU replaced all good but I can only blow cold air out not as before cold and hot ??!! The tech guys didn’t check there work before  I picked the car up?? Warm air was working prior to the work going ahead ??

Maserati are picking the car up but said it’s a warm air faults!!! Despite it working on the day I took the car in ??

Any comments ??

I would usually do a battery reset first, then check all the fuses. It must be something simple if everything else is working. Otherwise a possible problem with the heater core element.

I had a noisy AC compressor replaced with a reconditioned one by Emblem and the noise has now gone.
