My car's ac has no air coming through the vents..I checked the fan for suspicion of rat nest, but there is none to be found..so to check, the fan spins almost perfectly, hooked it all up and still nothing but small breeze..I have had multiple rat problems in the past and possible leftover from nests from running before getting nests completely out..

Has anyone had similar problem, or know of a possible problem? What should I do?? Any help is great!

 

Can you feel any air coming out of the defrost vents or heater vents? Could be the deflector stuck in a position or a broken or disconnected cable on the selector.

 

There is actually a small breeze coming through defrosters and heater vents when switching option around as well..how would I check the deflector and cable?

 

well, if the deflector is working correctly, you will hear air coming out of the defrost vents or heater when you move the selector to those positions. If you get nothing but the same slight air flow when you move the selector, to those positions, then something is wrong. You can pull the trim piece off and remove the screws and pull the control out and run the cable to see if it is disconnected or broken. If all is hooked up and the fan is blowing as it should, then somewhere in your duct work you have a blockage.

 

Alright, today I went with jtsk and looked at the cable to check it and it is tight and moves, so have feeling that's not it..we also hooked up the blower motor completely, but with it running to the battery for power and blew through the vents like old times! Super strong! So ruling out clogged ducts..

Why would it run through the vents perfectly hooked to the battery, but not to the original wires? What should I now? (Besides toggle switch lol)

 

Ok, sounds like either a bad wire or connector or possibly corrosion. Try looking at the wiring to see if you see any melted wires or evidence that some have overheated. If I am not mistaken, the wires for the blower connect on the firewall near the tranny dipstick location on the passenger side.

 

i had the same problem 2 weeks ago . i finally found the power wire from fuse block to the switch was the problem . look behind the control panel for Htr/AC the one with the levers & switch . behind it you will see a brown wire with a gray dis-connect . the dis-connect had corroded & allowed no power to pass to switch . cut gray dis-connect out and connect wires . worked for me . i also live in ms. close to the coast , i know how brutal it is with out A/C . what part of ms. are you ? good luck .
