Where is the blower motor on a 93 nissan altima

Blower motor resistor is bad common issue with sentras, best to have a qualified Nissan tech replace it, due to the location of resistor

sounds like a mouse attack to me. mice get into the heater vents and blower motor cage and make nests. those can throw your blower motor out of balance, thus resulting in the noise and then the motor just gets jammed and stops operation. but it could be just the blower motor failure it self. have it checked.

check for loose wiring by heater blower motor if that dont work,take the blower motor out and check it to see if its any good by using two wires connect them and check blower motor on battery posts if it turns then its not that

Check the direct connection to the blower motor. Check the fuse. Sometimes you can try to put it on high and try hitting the blower motor to see if turns on. It may also be the blower switch or the blower itself.

THE BLOWER MOTOR RESISTOR IS MOUNTED BETWEEN THE BLOWER HOUSING AND EVAPORATING HOUSING.

CHECK FUSE TO HVAC CONTROLS ALSO MAKE SURE YOUR BLOWER MOTOR IS RUNNING.IF NOT.CHECK FUSE.IF FUSE IS GOOD.BLOWER MOTOR NO GOOD OR YOU HAVE FAULTY CONTROL SWITCH.

blower motor resistor is located between the blower motor housing and evaporator housing.you have to remove glove box to get to it.

did you hydo lock motor with fuel? or do you mean the engine wont start?

It's behind the glove compartment. I had to remove about eight screws to pull of the glove compartment door and glove compartment molded plastic trim. If you are looking for the blower motor resistor. I found it. The blower motor is the roundish part on the far left hand side of the glove compartment opening. Out of the bottom of the blower motor are four wires in a common cable with a connector at the end. Disconnect this common cable connector. It is connected to the blower motor resistor with two screws. It will look like you are removing a connector, but the back side of this part has a what looks like a fin cooler. That part in your hands is the resistor (really) The part number will be on the connector P/N 27150 1E400
