I went through and checked all codes on my car today using the system under the hood. I got a code number 417 on the A/C system that says "Passanger's side interior temperature inlet fan seized". I looked in my Haynes manual but see no reference to this. Where is it located and how do I get to it?

 

Look inside the car just above the passenger door. There is a tiny hole within the grab handle. Within the hole is a temp sencor that is fed by a small fan. That fan gets clogged with dust. Usually sucking on the hole with a vacuum will clean it out. Once cleanned out, the fan resistance should be reduced, the climate system will sense this and the fan will start working again. This should stop the code from setting again. I've never had to remove the sencor unit for any further cleaning.

 

I tried this and the system works but the fan makes a lot of noise like the bearings may be gone. Where is the fan and how do access it?

 

After removing the grab handle, the sensor grill will pull straight out without too much force. Be carefull with the plastic parts - our cars are pushing 20 years of age. Try using a tiny art brush to loosten the dust on the fan inside there. Then some compressed air to blow it away. Finally some spray lube for the fan motor. Hope this helps.

 

OK so the fan is right behind grill, that helps a lot.
I had more time today to check this out and the noise I am hearing is coming from the center of the dash panel when the A/C is on. It sounds like something is spinning in a loose bearing. If I run the A/C and the noise starts and then I turn off the fan I still hear it. Any ideas on this anyone?

 

UPDATE
I replaced the fan and sensor assembly with one from Pick N Pull and all is good. Word of advice/warning, the hardest part of this is unscrewing the mounting screws with out damaging the head liner. The outside screw is no problem but to get to the inside one you have to pull the head liner down and get a torx bit in there with out pulling enough to damage anything.

 

I just cleaned out both of mine a few days ago when I replaced my head liner with one from U-Pull-And-Pay. It (the head liner) could not have been more than a year old.

 

A little shot of compressed air can work wonders on them.

 

A little shot of compressed air would have worked out better for me than pulling the dust out with hemostats. At least it gave me something new to take apart. The attached pictures show the sensor and if you look in the hole you can see the little thermocouple that I broke the wire on.
Picture #2 shows the fan itself separated from the body of the unit.
