Hey guys I need some help please,
Well the other day my a/c just quit. Strange thing is I can hear the fans on the outside kick on everytime I turn the air on. Only thing is nothing at all is coming out inside the cabin. No matter how high I put the fan switch on what setting I put it on I have no air coming inside the cabin. I check all the fuses they seem fine any other ideas or what to check where to look. Thanks guys.

 

Anyone? I need some help Please not sure what relay to replace since fans are working but blower inside is not. Tested the blower motor it's good.

 

Did you try re-filling it. Pepboys/Autozone has these niffty little bottles that can not only add more refrigerant but also tell you the level of the stock amount.

EDIT:
I just realized I might have mis-understood you. You are not saying that the air isn't cold, but that there isn't any air coming in to start with (man that's a lot of negatives...)

 

Dont do that ^^
Sounds like the blower motor to me .If the car still has warranty go to the dealer .

 

Checked the blower motor took it out and hooked it up to a spare battery started right up. I hear online about a bad resistor where is this resistor located??

 

I would say either the resistor , fuse , interior switch unit or relay .

Usually the resistor is located between the heater core and blower motor units .

 

Got ya thanks for the help anyone else or anyone with a Ralliart or evo have this same problem.

 

Mike, it's the blower motor resistor unit. It's fairly common and there's even a TT article about it.

If you remove that lower panel underneath the blower motor (2 clips under glovebox and pull outward) and then look upward, just to the left of the blower motor, towards the front of the car, you will see a black square with 2 philips screws holding it in. That's your culprit.

 

That thing with the big heat shield on it? I checked all the relays they all seem good and all fueses are good. Any way you can pull up the TSB for me. Thanks Alot.

 

Yeah, it's got a bunch of metal fins on it, looks kind of like a heat-sink on a circuitboard.

It's actually not a TSB, it's an internal Mitsubishi "Tech Talk" discussion topic since it was noted as a common cause for this problem, but the problem itself is not common enough to warrant a full-out TSB for resistor failures.

I'll see if I can pull something up for you, though.

 

Okay thank you. Do you think it will be under warranty if I have close to 59,000 on my car or should I just buy a new one and do it myself.

 

I believe it's only covered for 3yr/36k, doesn't hurt to call and ask though

 

Okay thanks a friend of mine is gonna let me swap his in before I order a new more to make sure 150% that it's the problem. Thank you for all your help

 

Update. Took blower motor out of car tested it with car battery it turn on and spins freely. Swapped resistors with my friends car still didn't work. Checked all the fuses still nada. Idk what else to do??? Looks like I gotta take it to mitsu.

 

Try the relays or might be the actual switches .
