my HVAC is working fine so far but the maximum heater temperature is too low. Depending on the outdoor temperature the heater gives not more than approximately 15° Celsius. Temperature control works fine from hot to cold and reverse, A/C works too.
Ran the auto diagnostic procedure as explained here by KHLOW2008. Error code is 34 - Engine Temperature Message Not Received.
How to proceed?
have the same problem?
