3200GT Only hot air!

[boomerang]

From one problem to another.
Noisy fan cleaned and solved, but still the problem with hot air always, even in max cold setting.
Did forced reset, showing AA and 00, so everything should be fine.
But only hot air…..anyone ideas?
Btw: aircon NOT active yet, system has to be re gassed.

It’s either the dial or the flap presumably. Does the direction dial work?

 

[boomerang]

Yes, you can hear a lot happening when direction is changed.
Just not when temperature is changed form hot to cold.

Hi Luc, I have a spare hvac control unit. If you want to borrow it to check if the malfunction is caused by your control unit, then let me know!

Hi Danny, thanks for your kind offer!
But this morning I disconnected the unit and plugged the unit of our parts spender on.
All working fine! So indeed, the control unit is the problem.
Very happy the dash does not need to come out for this.
