No, it contols ONLY the variable speed of the cabin circulating fan. However, my Hayne's Manual states that CR-V's are NOT equipped with blower resistors, they are equipped with POWER resistors. The manual then states that.., "power resistors cannot be checked with conventional test equipment but can only be diagnosed as faulty through process of elimination." It then gives a 1/4 page procedure with pictures as to the step-by-step method you must use. That material is too lengthy to be quoted here and, in any case, is protected by copyright. I recommend that you purchase a manual or go to your local library and see if they have a copy of the Hayne's manual for your year CR-V and follow the procedure set forth.
shaking the blower resister
Yes it does power has to go thru it first and if current is to high it will blow the resister as like a fuse
When you beat the blower motor, you are probably shaking the blower resister. The resister is what controls the blower speeds and is probably bad or loose.
The heater blower resister is under the dash on the passenger side. It is inserted into the side of the blower motor case.
Behind the glove box.
location of resister for blower motor on 1997 s 10 blazer
I hope you checked the fuse.
Remove the HVAC rear module auxiliary assembly.Disconnect the electrical connectors from the rear blower resister auxiliary.Remove the air outlet duct from the rear blower motor controller auxiliary.Remove the screws from the blower motor rear resister auxiliary.Remove the rear blower motor resister auxiliary.Replace the resister and install new thermal gasket.................
It is under passenger side dash behind the blower motor.You must remove blower motor to access it.
Most likely the resister is burnt out. When you use less than full blower, the blower speed switch shunts the 12v power though a resister to drop the voltage to the blower motor, slowing the blower speed. When the multi-speed resister is burnt out, it is, 'open circuited'. So no electricity can pass though to the blower. When the blower switch is on 'full', the resister is bypassed, allowing full power to the fan motor for maximum speed. It should be located under that dashboard in most vehicles. Just trace the wires from the switch to the resister. Warning: a working resister can get very hot when power is going though it.
It's close to the blower motor.
The blower resister could be bad, or the blower switch could be failing. Check the resister first, it is commonly mounted at the rear of the blower housing under the hood.
