I replaced my heater blower motor and ever since this the air that comes out is not much. Is there something that needs to be replaced or did I not connect something right any help would be greatly appriated. It is the middle of winter and I woul like a little bit more heat when it is in the teens and blow.

Was it auniversal motor adn you had to splice on your own connector? If so be sure the motor isnt wired backwards. If not, does it change speed with the selector like it is supposed to? Is it trying to blow out of different vents at the same time? Like floor and vents

No it was not a universal motor. As for it changing speed I do not think it changes speed. When it is on high it will try to blow out air and when it is on low nothing happens. And yes it seems to be blowing out of all vents when it is on.

Was this the reason you replaced the motor in the first place? If it doesnt change speeds, you may have a fan speed resistor out. Need to put a meter on the fan power and see if the voltage varies with different fan speeds. If you put it on just vents, will the air change? Or try just floor to see if the mode door is working properly.

Do the dash controls work ok? Vent selector. Did you match them up to be sure they are the samemotor? Does the motor definitly change speed or is it stuck on low, like the resistor is burned up? Need to check voltage at motor with meter on different speed settings to be sure resistor is good, bad motor can take them out

I had to replace the resistor with moter because I broke it when I replaced the motor.

Did you match up the parts before installation to be sure they are the same? Have you checked anything else I have suggested?
