I am new to this site. I was very impressed with what the users of this site helping each other. I am not a mechanic but I recently started doing those DIY.

I have read a lot of answers referring to the problem that I am having and my head is now just spinning.

I am not an electrician or mechanic; I was just trying. This is how it started:

My blower stopped working. I had my friend; a mechanic check it. He stipped one of the ground wires and attached another wire to it and the othe end to the vehicle body. It started blowing but just at the high speed.

Gradually, the blower started working intermittently. Sometimes when I hit a bump. Eventually it died. Now I was tring to fix it.

I have tested the blower with the battery and it works. I have replaced the blower resistor; still no luck. I replaced one of the relays; still no luck. There is voltage; more than 12v getting to the blower motor.

The fuse is ok. When the blower switch is engaged; I can test continuity to the blower motor. When I test for voltage at the switch; only one wire has power. I am not sure if more than one wire should or not. ALso; there is no power going to the resistor; and yet they said in the munual that if ther is no power from the ristor to the blower, then the blower will not work.

When I unplug the wires going to the resistor and leave the blower swich engaged; I cannot find any juice on any of the wires.

Is it the swich that makes power available to the resistor. I am totally confused. Please Help.

Thanks in advance

If you get intermittent operation, like when you hit a bump, I'm thinking you've got a loose wire somewhere.

the blower motor is hot at all times, speeds are controlled by ground. your problem is .you need a new heater motor

I have replaced the blower motor even though the one that I removed was working when connected direct to a battery. When I put in the new blower motor it was running fine with the original blower motor switch but only at certain positions. I replaced the switch and the blower works a all speeds now. It looks like I had multiple issues.

Now the problem I am having is that there does not seem to be air coming out of the vents evsn when the fan is blasting on High. What next.

Also I would like to thank those that replied to my problem. I made me have some direction. Thanks again.

That's cool. You've got everything working properly ... now all you have to do is examine the vent system and see what's stopping the air from traveling -- blower to vents.

What year is this Camry? I'm having a similar problem with the wife's 97 Lexus ES300. Blower doesn't work and then hit a bump or power car off and back on and it works again.

My daugher has a 1990 Toyota Camry. The heater fan and power seatbelt both stopped working at the same time. There was a blown fuse and we replaced it. We reset the circuit breakers. The fan and seat belts are still not working. We have purchased a new blower motor but have not installed it as of yet. The old motor as in the post above works off the battery. We thought there may be a relay problem. Should we try the new blower motor or replace relays.

My 1991 Camry also has a (heater a/c) blower that is failing. Going over a bump can either stop it or start it . Once started, it remains working for a few days until another bump comes along.

My question is this. How easy is it to change the blower motor. It appears to be below the glove box, but I don't see how to begin.

I was working on one of these the other day at work was very baffeling but what i found was the motor would would work some times but not others. O tested the blower motor in the can and it had no continuity so I pulled it and tested it again just to make sure and now it had good continuity, I thought I pulled it and didn't need to but then when i spun the motor the continuity would go open then to 0 ohms then up to the 20 replaced the motor now good as new.

This old thread popped up again? I had almost forgot about it. My wife's Lex blower started working again and has been doin OK.

Hello,

I have a similar problem. Could you please tell me where the blower motor resistor is situated?
I have gutted the front console but can not find the resistor. Any help would be welcome.

Usually when a blower motor has an intermittant on/off problem, and tapping it or going over a bump fixes it, it means the brushes in the motor are worn down. Becuase of the commutator spinning, it wears the brushes on an angle, and when they get short enogh, they will stick in the holder, causing a no contact. A slight jar will free them up, and voila, it works again. Only real fix is replacement.
