Sometimes I need to punch on the passenger dash board in order for the ac to turn on (Chevy Impala 2006) someone said it might be the fan motor, how true could this be?

Next time instead of punch or smack reach under glove box and give a wiggle test to your blower or multimeter and check for voltage for an actual diagnosis ...


Highly likely, a sudden jolt can shock an electric motor into running but it won't last cause every time you jolt it you pit the armature and blow off a piece of brush so eventually you will loose the blower all together.


@Shlomo wont i need to remove covering for all that (please excuse me as I am very air headed when it comes to vehicles) plus i wouldn't know what a multi meter would look like. I mentioned my question to a "mechanic" he said that would be it and was trying to charge me around $230 @Tennisshoes thanx for your response if indeed your right i saw a video where it doesn't look to difficult to replace


Blower motor or Fan motor are the exact same thing right??????


take your automobile down to your local shop and the technician should be able to diagnose the problem with the malfunctioning ac


Heater blower motor is for the heat and A/C system, the other motor is called a cooling fan motor or radiator fan motor. Heater fan motor id for heat inside the car, radiator fan is for heat created by the engine compartment

@tennisshoes so what likely am i dealing with? when i "punch", which i actually smack, the dashboard simply for the reason of wanting my air conditioning to start blowing, in which it does


The most common would be a bad heater blower motor, the next would be a heater blower motor relay and finally a bad ground to the heater controls. All of the listed componets can be started by whacking the dash if they are the least little bit weak.

@Tennisshoes thanks for your help i will save money & replace the blower myself since i don't see it difficult in doing; hopefully all is well after that, If not i might have to prepare to dig into the bank for somebody to change out a resistor or bad ground


Ok. Good luck, I can tell your going outside your comfort zone on this, just take your time and you will be fine.

@tennisshoes quick question, both front wheels and 1 back wheel read 215/60R16, the remaining back wheel reads 205/55R16, please tell me this wont affect my car in any negative way??
