Aux canceel ac errorE1 - AC Cars & Trucks

Check your cars aux fan maybe its not working properly

Yes the AUX fan must come on when the the AC is running. If your car is overheating change the water pump and thermostat.

there is a 'high pressure' at your a/c compressor. this is commonly caused by a faulty aux fan (fan for the condenser). have your aux fan serviced.

the AC Clutch relay is in the small aux relay panel under the hood. There could be a few relays in there, depending if DRL and if the truck is a 4x4, take a look at the owners manual on page 244 & 245 to locate which one is for the AC.

probably the aux fan for ac check if your ac pump is disengaging when ac is off if no either unplug ac pump or track down ac relay and change may be stuck open make sure your ac is off.

Have you checked the Aux switch near the bottom of the center control console.
There should be a knob with: Aux, Off, 1, 2, 3. This is the switch for the rear AC blower.
If the driver wants to control the rear AC, use the 1, 2, 3 settings.
If you put it on Aux, Than the rear AC is controlled by the passenger in the back seat using the extra controls located on the Overhead DVD player. (The front AC must be on the rear to work)

One should be by the drivers side strut mount and the other up by the Aux fan in front under grille.

are you talking about heater blower motor, if not working check fan resistors, ac needs recharged, or you have a leak in ac system.

I was able to contact a local service man who works on vehicle electrical. He directed me to a fuse box on the left side of the engine compartment specifically the #1 and #4 fuses. He said the fuses will burn and that is a common problem with the aux power ports and their locations. inspecting and replacing the fuses ended up being the fix.
