2003 AC unit problems

Upon taking my car out of storage, i found and cleaned out a field mouse nest nestled inside the middle of my recirculating fan behind my glove box,

the problem is that now after removing the fan motor, cleaning it and the housing and re attaching it, my fan will not work on speed settings 1-3 but blows on setting 4.
the strange thing is that when its turned on four, the AC light cuts off and only pumps regular air through the car, so my problem is that my car pumps no air when running the AC, and when its pumping air the AC cuts itself off.

any ideas how to fix this, and or what the problem is?

    I haven't found anything in my 03' Lancer fan but the AC turns off by itself. The mechanics could not find the problem but I will mention this to them.

There is a resistor block in the blower housing, it could have been damaged when the field mouse nested on the blower.

it is coils of wire ( nichrome wires) with 4 wires connected to a socket . this slows down the speed of the motor.

tnx 4 using fixya,

My 2001 toyota sequoia smells like a burning smell when i turn on the ac what is it?

You most likely have leaves or a field mouse nest in the ducting and they are smoking when they get on the AC blower motor speed control resistor it is very hot. You can start a fire so have the blower motor removed and the leaves and or mouse nests cleaned out.

When starting each time get a really awful smell [like old urine thro the air conditioning] is it filters or need re servicing

Depending on the year it may have a filter. i would check and replace it, another thing ive found on many cars is that mice make nests on top of the filter for the heating/ac system and that smells bad, what i do is replace the filter and then turn on the ac or heat at low temp with high speed fan and make sure the setting is for outside air not recirculating and then spray grem and ordor killing spray into the vents, not inside the car but from the outside where the wipers are, this is where the air comes in from and also make sure to open door to allow the spray to exit the car, good day.

Is there a air filter for my ac/heater in my 2002 chevy blazer? if there is how do I access it? Also I seem to have some sort of nest(mouse I believe) in my venting sytem by my fan..any suggestions?

There is not a filter. Cleaning the problem of the pest can take awhile. And taking the dash out to get access to all the vents and conduit aint fun.

I would remove the heater fan and clean out the mouse nest. They probably climbed into the system through the outside vent.

Had same problem. Replace Blower Motor. Over a 100 dollars at local parts store, but found online for half price. About 30 minutes to replace.
6 screws to remove glove box, One plastic nut on kick panel and 3 screws hold the blower to the air box.

Blower housing maintenance

hi brian,

tnx for asking me, im sorry but i can't find a diagram for your car but if i can describe briefly, the resistor block is a plastic material on the front and it is screwed on the blower housing, air is supposed to pass through the wires because these wires are used to drop the voltage in order for the motor to have variable speed.and they glow red hot when currnet is passing . the wires are inside the housing where the blower takes off. you were able to locate the blower and when you bring it down , the reiitor block is just around there.

sometimes this resistor block is in the form of a pysical white block of ceramic. you can not see the wires cause they embedded it in the ceramic.

if you see a white block inside the blower housing, then that is the reisistor block. if it is a block, then it can not be repaired. it must be replaced.

yes, the flap that you cleaned id the recycle flap.

there are no more blockade after the blower. it is already the evaporator and it could be blocked if it is dirty.

hope you find the resistor block.
tnx again 4 using fixya,

Horrible smell coming out of the ac system

disconnection your fan has 3-4 screws and check for a dead mouse or two and bits of dried grass. They like to build nest in there. If your car sits for extended amounts of time that seems to be when the animals call it home. It was not a pleasant job for me to get them out you just have to get rubber gloves and do it.
