The ac unit compressor will run when it is in defroster mode and heat setting is on.
You've got trouble with your heater fan - or the motor that turns it. Same fan for both heat and AC.
yes, if the ac unit has 2 zones, you will need a thermostat for each zone. if the ac unit provides both ac and heat, you can connect a thermostat for each. not a good way to go. better to use 1 therm in that case that has a heat-cool switch on it so the unit is not putting out both heat and ac at the same time.
Usually 1 working day and atmost 2 working days.
i have the same issue let me know if u figured it out
if the rear ac is working then you probably have a damper door that is inoperative. this is in the heater/evaporator box. so if it isn't working then you will be heating and cooling at the same time out of the heater box.
fuse related issue! , my car do the same, try to get the manual and replace the fuse if necessary, also look over your blower motor assembly, good luck
it could be the blower switch
The thermostat may be stuck open, replace it. No ac belt won't effect the heater.
An electric fan might not be working.
In winter season split AC is working better than window AC and the heating is not decrease like windpw AC the working system is the same but heating ability is not the same why?
My crown vic 2000 when ac runing that time fac not working pls help me
sounds like the blend doors arent working in the heat/ac plenum. take a look at all your door motors and see if they are connected and working properly
