Depending on the type of car you have, it can be very easy or very difficult. The easy ones will have a circular metal plate on the firewall with about 10 very small screws around its circumference. Protruding from that plate will also be a small usually black can looking object about the size of a soup can. This is the fan motor. Just disconnect positive terminal on battery before starting, then remove the series of small screws. They are usually a hex type screw, not a slotted. The whole assembly will lift out and the replacement will look just like this one you've removed.
That's the easy one... the difficult ones are under the dash, passenger side inside the heater box. They look like the one I described previously, but usually require a lot more disassembly of surrounding components.

Best of luck!

Estimate to replace ac/heater blower motor


Cost of the new motor plus half hour to 45 minutes labor time- just depends on what is in the way of getting to the blower motor. It is usually a pretty easy job, the fan blower assembly is retained by 3-5 screws. Take it out and put fan assembly on new motor, then reinstall.

Blower wheel fan


The Blower wheel fan ....where is your question.....?..Yes it can be changed without replacing motor...Very delicate ..be careful while changing it...If fan isn't running it could be a Relay,Resistor,Or faulty motor....Also faulty fan control panel....I don't recommend trying to replace the fan alone..If fan is damaged it can also cause abnormal wear to motor....replace the complete fan/motor assembly...
