hi i had the belts tightened a little today from belt squeaking now the ac doesnt work. It runs but no air is blowing out i'm really frustrated now can anyone help me. Thank u

 

Going to need some clarification.

Do you hear the compressor engaging? Is it no air at all or just no COLD air? Are you sure you properly tightened the belt?

 

Im having kind of the same problem...I have cold air when the a/c is turned on, it is not blowing but you can feel it if you start driving....I was told my blower motor went out but took it off and ran a straight line to it and the motor turned, all fuses and relays are in good condition, amp meter says electricty output is good and I was told it might be the resistor so im going to check that tomorrow

 

Seems common for the blower resistor to go out. Usually though there is also something up with the blower motor itself (bad bearings etc). These blower resistor is pretty accessible (under the dash just behind the glove box. The fan motor, you'll need to remove the glove box to get to.

My bet would be on the resistor at that point.

 

oh yeah, another thing is that I do not have manual controls...i have a climate control, so now i'm being told that I have do not have a resistor...

 

You still have something that controls it. I believe it's called an amp for auto controls, and a resister for manual controls. Call Dave B to confirm...

 

it was called a blower motor power module..... a nissan exclusive part

 

the problem went out by itself so we'll see what happens hopefully nothing. Thank u
