climate control issue, could use some advice

my CCU appears to be in working order, when i select defrost, or change the temp, or how hard to blow it displays everything and turns on and off just fine but the blowers usually dont work but on random occasions they will and when they do the air wont get hot. im not sure if my blower motor is out, or if it might be the CCU, and as far as the heat im pretty sure my heater core isn't bad so i was wondering if it could maybe be the pollen filter ? any advice to help me pinpoint the issue would be greatly appreciated.

Check this web.

I did it 10 minutes ago and now it is running!!!! I am Fuc....ing Happy!!!!!
I bought the capacitor @ FRYS.com

My climate control used to start working and stop by it self and one day it stoped working at all. I chahged that #$%#@% capacitor and now it is working.

I love the guy hwo did it!! (Richard Swope)


good luck

That fix is more for when the display gives out, too. That capacitor is part of the power circuit for the CCU and if the OP's CCU is displaying properly it is not likely this capacitor that needs to be fixed. In this case it sounds more like a Final Stage Unit (otherwise known as Final Stage Resistor), or maybe the blower itself. The cabin's micro-filter is pretty easy to swap yourself, though I haven't done it myself.

Good luck!
