Yea yea so this has been sparsely posted and talked about, but none of the threads with common issue have been solved.
I have an 02 MCS
, suffered from the bad fan resistor deal, replaced the fan assembly about 3-4 weeks ago, car has ran excellent, and is bone stock. I noticed today with about 90 degree ambient heat with the A/C on the light started blinking and the air went warm until I got moving it worked itself out and blew cold air again.
Ok obvious to me, something in the fan system isnt working right? Got home with A/C running, got out noticed the high speed fan is not on, but the P/S fan is WIDE OPEN! Checked the fuse box for blown fan fuses, nothing blown all fuses intact and working properly. Get back in the car, noticed it is starting to heat up so I shut it down.
Let it cool off for about 10-20 min, start it back up without the A/C running and the radiator fan STILL NEVER cuts on neither low or high speed. But with the A/C switch off, the P/S fan is NOT running. When switched back on the P/S fan immediately runs wide open, and keeps running even after car shuts down (for roughly 1-2min).
I assume, and probably correctly, that the P/S fan system is tied into the high speed radiator fan system, if this is the case, can anyone explain to me or point me in the right direction of why the radiator fan is not switching on at all even with the A/C on? Or why the P/S fan runs wide open with the A/C switched on and continues to run after car is shut off?
Just looking for a few pointers here.
All fuses good (including all fan fuses).
Radiator fan is only about 3-4 weeks old, and has been working fine.
Power Steering fan is fully operational (just not sure if operational at the correct time it should be).
Fan assembly does not switch on at all even with A/C on at idle.
