HVAC Not working AMG GTS
Hello everyone,
16 AMG GTS. I recently replaced the HVAC control module due to having zero climate control functionality “wont turn on, no lights on push button unit” and “no communication with AC control module“ when scanned. Also had “malfunction” warning message in center gauge cluster and thought they were related. Now with the new HVAC control module, the climate control System turns on, I can control fan speed, air temp, diffuse location, etc. However, the air only blows a constant temp (no hot, no AC cold air) no matter the temp set. All codes cleared and still have “malfunction” warning light on and scanner is showing no dtc’s. Any help is appreciated. Thank you.
