I'm just curious to see if anyone has had issues with your fan (for heat and air). As of last night, my fan only comes on when I turn it on the high setting. If I turn back to 3, 2 or 1 the fan turns off. Also, this may be a dumb question but does the AEM have any control over this?

I'm going to give Mitisubishi a call but I wanted to see if anyone has had this issue before.

Thanks for the feedback guys/gals.

are you talking about the actual heater/ac fan or the engine fan?

 

03 VIII's have all kinds of issues with heating/air controls. There is a TSB...

 

Sorry, I should have been a litte more specific. I'm referring to the fan in the car. It only comes on when I turn the knob to 4. 1, 2 or 3 doesn't work.

 

Excuse my ignorance but what is "TSB"? Thanks

 

Technical Service Bulletin. Cars that have known issues will usually have TSBs, which are sorta like car-part recalls, and most of the time the fixes are done for free by the manufacturer at no cost (For example: My seatbelt airbag sensors in the Porsche, '99s have a TSB to get them fixed with different connectors because the original ones had issues, would've cost me around 500 dollars, the dealer did it for free, and I definitely don't have a warranty.)

Take it to the dealer and have them check it out, I bet something is wrong with the switch. If the fan on 4 is running at a slower speed it could be a power issue, if it runs at normal speed then it is probably just something weird with the switch.

 

you need a new resistor....
thats all that is.
not sure where its located at in these cars, but it shouldnt be to much for the dealer to fix it

 

Well, I just got off the phone with the dealership and service said the same thing. Thanks for your help!

 

I agree, resistor is probably bad. Position 4 allows full voltage to the fan motor, where 1-3 are reduced via the resistor. If that is open (broken) then no voltage flows, no fan motor spins.
