What is wrong with blower sometimes it blows the airconditioner compressor is on but the fan won't blow?
Bad fan motor (windings opening when they get hot)
Bad or worn switch?
The same as any air conditioner. The process uses compressed gas to chill a screen or vent inside your airducts. A fan then blows through the vent cooling the air temperature as air flows through. Parts of auto A/C include; an engine mounted air compressor, pressure hoses, ducting, a blower/vent box ( usually under the passenger side dash), and a thermostat.

What if the AC on your 97 5.7L 4 door 4WD Tahoe blows very cold but does not blow powerfully even if it's set on high?
A vehicle air conditioner has two basic components; the compressor, and the fan, or blower. If the compressor is working, the air coming out of the vents will be cold, but if the blower is not working, the air will not come out very fast. Hot wire the blower to the battery, to bypass any fuses or switches, and see if the blower will run. If it does, but will not run when connected normally…
Why does a 96 Contour blow the blower fuse when the selector is put in the defrost position any speed but not when on front vents?
The AC works only on the highest settin and when it blows its making a noise what could be the problem?
The AC and heater are completely different subsystems. The heater relies on heat generated by the engine and circulated by the engine coolant (radiator fluid) while the AC uses a belt driven compressor and separate fluids. Their only normal commonalities are the blower motor (which you said works), the ducting and the control head.

Is there something loose with a fan blower on a 1994 Olds Achieva if sometimes it works and sometimes it does not and at times when it does not if it hits a bump in the road it blows again?
The blower motor is worn out. My 95 Achieva had the exact same problem and I had the motor replaced. It cost $168.00. $70.00 for the motor and the rest was labor. I had the same problem in my 92 Achieva S. I agree, the blower motor is going bad. I bought a rebuilt one for $30.00 and installed it myself. It is easy to do.

There is a resistor pack under the dash next to the blower motor. I had the same problem and eventually the blower stopped all together. I was in no hurry to spend the $100+/- so I tried a lot of trouble shooting, but after talking with 2 Volvo Technicians they both told me that it was the resistor pack without looking at the car. Try looking on eeuroparts.com, $65 or $136 depending on whether or…
