HVAC

Of course when I went to take the truck in, it was working fine (got up to -16C), but they did the procedure anyway, It's in the cab so not sure why there is a coating on the terminals, but they leaned them up and the HVAC seems to be working fine.

As owners post their anecdotes, would you please also list your model year and build date. Would be helpful to see if this is an issue with a particular batch of vehicles or if it’s a model year issue. Thank you

If the issue is trapped air in the cooling system, why not use a vacuum cooling refill kit available at harbor freight or anywhere else? You hook it up to an air compressor, vacuum all the air out the system, close to system, wait a few minutes to ensure there are no leaks, and then refill with zero air. Am I missing something here?

Vacuum, My memory is shocking, i keep saying pressurised, Vacuum bleed is what the IA technician told me that my dealer needed to use to get ALL the air out. Obviously they didn't as I just had to keep using until it was gone.

Strangely for the first time in approaching 3 years of ownership, my hvac was a little temperamental yesterday. It was blowing very hot air even with temp on coldest setting. Only way to get cold air was to press auto, then cold air straight away. Turn auto off and hot air straight away. What’s that all about. Software issues I presume. Also now have an ecall error. Batteries fully charged and 34k + miles.
