Blower not working properly

What did that 10A fuse control? (its written on the fuse box legend)

check heater ground and control relay..

If the problem is a lack of air flow from the vents, and you suspect the blower motor is not running at times, you would need to test the blower relay and blower motor for power and ground when it is not working.

Good Evening, on the drivers side below the air cleaner assembly on the frame rail is a blower control relay bolted down to the frame. First off check your fuses and relays for your fan and if those check out ok then I would say since it is a very common replacement part that it would be the culprit. You could also test the fan itself by applying power to the fan. Hope this helps.

Does the blower actually start working at speed, or are you merely getting air flow due to your forward motion? Check the fuse for the blower, and the switch. Use a test light to see if you are getting power to the blower motor. Is the ground connection for the motor clean and tight? If you have power, the blower motor may be defective, or something blocking it from spinning.

take out the blower motor
if the bearing is ok

use a vacuum cleaner to suck out the debris in the piping

Check the heat/ac relay first making sure it is working.remove it clean the contacts and reattach. Then check the Resistor component. It is usually located near the blower or on the blower motor itself.It is attached with a couple of screws and a plug between the blower motor and the wiring. Please vote if this helps you.

need heater blower resister that controls blower speed.

if it is auto temp control the power module could be bad....if is regular style where you control blower speed the blower motor resister is bad

burn that VAN ! !
