Operation: The blower motor is responsible for driving the fan that blows air across the heater core. Advice: If the blower motor is not working, first you must determine if the blower motor is at fault or if the problem lies in the speed control circuit and/or wiring. One of the quickest ways (depending on accessibility) to test a blower motor, is to hot wire it. If you disconnect the wiring harness and apply battery voltage to the blower motor terminals and it does not spin, then you know that the motor is bad. If it spins, you know the problem is somewhere else in the system. Most blower motors will have two wires or terminals, a positive and a ground. Check the repair guide's wiring diagrams to determine which is which. If you do get it backwards, don't worry. Reverse polarity will only cause the motor to run backwards. For testing purposes, if the motor spins in either direction, the problem lies elsewhere. The one wire design gets it's ground through the blower motor mounting, so the single wire or terminal is your positive connection. Recommendations: Repair guides.I don't know but I am about to attempt it. I will post some advice and or pointers here after I have successfully completed the task. If you do not see anything here from me in a while, it means I was not successful. :-(

Lets hope that is not the case! It is not hard to do, but you have to remove the glove compartment and nearby trim to get to it. Hayne's has a good description of the procedure in their Camry service book. Note that the blower itself is held in with Torx-head screws.

I found that removing the passenger seat (which is not hard to do) makes the job a lot easier and reduces the total time to replace the blower. Otherwise, you have to work upside down and twist yourself around the seat.

Did certain speeds on the blower fail before it stop working alltogether? If so, I'd wager it's the blower relay - which is an easier and less costly fix.
