Vw Jetta Ac Fan Not Working

The brushes inside the motor were stuck and needed cleaning.

Vw jetta ac fan not working.

A bad fuse the first thing to check with any issue related to the car s climate control or electronics is the fuse box. Both fans and compressor not working all fuses good and all grounds good and an extremely high 134a pressure on both the high and low side. Large fan was working almost constantly at full speed and ac was fine. Car ac not blowing cold air.

Valve for air conditioner pump broke and sent metal fragments through the system necessitating replacement of ac pump. I ve got a 2004 mk5 golf tdi 2 0 and when i bought it a while ago the small fan was not working at all. While there are a variety of reasons your volkswagen jetta air conditioning won t work the most common 3 are a refrigerant leak an electrical climate control. Repairpal will help you figure out whether it s your ac refrigerant leak climate control electrical issue ac compressor or something else.

To make it run or see that you have a problem turn on the a c and put the fan at a non zero speed. If there was a short or a surge in the system the fuse might blow to protect the delicate electronic components from damage but in so doing will render the system inoperable until the fuse is. A couple of days ago i tried to operate the a c and it wont blow cold air at all however if turned to hot it works fine. I just replaced the volkswagen audi auxiliary fan for 26 86 control unit 1j0 919 506 k.

The big fan provides cooling air for the main radiator. Last repair was auto windows idiot designers put in plastic components. Only 30 k and today a 2 600 repair. The large fan was not working.

The fan should start running at its slow speed. My wife s 2002 jetta station wagon turbo has been nothing but trouble. The small fan is for the a c condenser it runs when the a c is active. It is the one that runs when the engine needs more cooling.

I bought the part on ebay swapped it out and instantly problem solved. Cooling fan not working that s 800.
