    I have no blower for my ac system, it worked fine yesterday and nothing today. I've checked the fuses and relays and all seem to be OK.

What is the problem? How do I fix it? Resistor Pack? Fan Control? Entire AC system?


your problem could be in your control switch panel itself. pull out the control panel and check the connections with a Probe Light Tester. The following video is for a Volvo but is used here only to give you an understanding of how to remove your A/C Control unit to check for poor circuitry. https://www.youtube.com/watch?v=SmCKFx1B4cA

AC blows cold air, fans stop blowing


I think you have a "variable speed resistor" problem, it's overheating. It's an electronic device usually located near or attached to the AC motor blower that controls the fan speed. This is a common problem with aging AC blowers with electronic controls.

My ac/heater fan stops blowing then it blows sometimes? The air is still cold just not blowing out. when it does blow it is cold.


replace fan speed resistor block if this only happens on lower fan settings if it happens on high fan speed also, replace blower fan
