1999 Montero Sport XLS: fan..Working perfect one minute, then dead.

Customer Question

I have a 1999 Montero Sport XLS and the a/c fan quit yesterday. Working perfect one minute, then dead. Does not run on any speed. The a/c compressor works, just no evaporator fan. Checked all fuses that I could find. No luck.
Need your advice...hope you know Mitsubishi.
Thanks.

Tim West :

Thanks for visiting Just Answer

Tim West :

You either have a bad blower resistor, relay or blower motor itself

Tim West :

First, at the blower motor relay

Tim West :

make sure there is good power to the relay on 2 wires in (one has power when the key is in run the other is hot at all times)

Tim West :

There should also be a good ground on one of the pins.

Tim West :

You can also just try swapping the blower relay with a "like" relay.

Customer :

Hi Tim,Where is resistor? Is there any way of telling which relay services the

Tim West :

If the blower still does not work, it's not a blower motor.

Tim West :

Yes, there is a relay box by the drivers left knee.

Tim West :

Do you know where I am talking about?

Tim West :

That is where the relay is.

Tim West :

Hang on I will get some pics

Customer :

Yes, I was in there yesterday.

Customer :

Where would I find the resistor?

Tim West :

1 sec

Tim West :

the resistor is located on the blower housing

Tim West :

WEll, actually between the blower and evaporator

Tim West :

Here is a way to check it and where it's at

Customer :

blower housing under dash I guess

Tim West :

click here

Tim West :

Thats right

Tim West :

Now I gotta just be honest

Tim West :

There is a new resistor

Tim West :

they made

Customer :

do you know if autozone sells those relays?

Tim West :

( I included the bulletin)

Tim West :

You can swap the relay to check it.

Tim West :

No need to replace it yet.

Tim West :

I think the resistor is more common

Customer :

swap it with another relay in the same vehicle?

Tim West :

Thats right

Customer :

how hard is it to replace the resistor?

Tim West :

I can't remember what relay is the same, but there should be one.

Tim West :

not hard, the book labor time is .5HR

Tim West :

30 minutes

Tim West :

Just remove the under cover

Customer :

I guess the voltage has to be the same so the relays are probably identicle

Tim West :

as shown in the picture

Tim West :

and you should be able to access it

Customer :
