I notice the strength of my blower motor isnt that great. Even if the fan is on high and the a/c is on max, it only seems to blow less that half as strong as my new grand am. At one time it definitely blew harder. Does this mean I need to replace it? How hard is it to do?

 

Your complaint is common. I recently replaced the blower motor to find that it blew twice as hard as the original (1985--hey, that's a long time for a motor of this sort). The replacement is very easy, straightforward, and cheap.

I have the same problem but the plastic case where the ac lines go is almost completely broke off on the side of the motor would that affect the vent with ac off?? The blower motor blows like nothing out but it did before the plastic was broken off.

 

Hey James...whats involved in replacing it?

 

This from the manual:

(Before starting, I'd stuff a towel/rag between the blower motor and the cowl to prevent losing a screw in the bowels of the motor.)

1. Disconnect the negative battry cable. If necessary, remove the diagonal fender brace at the right rear corner of the engine compartment to gain access to the blower motor. (If I recall correctly, I couldn't remove the blower motor without doing this.)

2. Disconnect the electrical wiring from the blower motor. If equipped with air con, remove the blower relay and bracket as an assembly and swing them aside. (Not a big deal, three or four screws.)

3. Remove the blower motor cooling tube. (A rubber tube at the lower righthand side of the blower motor. Mine simply pulled off.)

4. Remove the blower motor retaining screws. (There are five or six. The lower left can be a pain. Be patient.)

5. Remove the blower motor and fan as an assembly from the case. (You may have to manipulate the assembly a bit to accomplish this.)

(The new motor probably won't come with the fan attached--the fan is a white or yellow cylinder. Simply swap it from the old motor to the new.)

6. To install, position the blower motor into place and install the retaining screws. (I'd advise cleaning the insulating material from the case to get a tight fit. You might consider automotive strip caulk or some other product to help seal the motor to the case.)

7. Install the blower motor cooling tube.

8. Connect all the electrical connections.

9. Connect the negative battery cable.

Taking it slow and easy, the job is probably no more than an hour.

thanks!

 

My '87 T/A blows much harder than my '92 Camaro. And I will bet it is the same fan. Go figure.

 

sounds like a door in the vent system isn't opening or closing all the way.
