A/C-Heat fan rattling then siezing, blowing the fuse. 2002 Maxima

What is the outside air temperature when it locks up? Summer temperatures will cause it to lock up much sooner which is normal. If this is not the case you can get a replacement fan clutch at any auto parts store

check heater/ac fuses first replace if bad..see if there is power to the blower motor connector if so reconnect and check ground wire for the motor.. if still no blow, take motor out and test for operation with 12 volt power supply(battery charger) replace if bad..good luck

It's is very possible. You may be correct however don't dismiss the wiring. The wiring may intermittently short with movement/vibration and cause fuse to blow but most likely you are correct in thinking that your fan needs replacement.

The CLU is the compressor clutch - sounds like there may be shorted wiring in the clutch coil, causing it to draw too much current.

I believe the ultimate problem is with the blower motor itself.They can get water in them, dirt and general grot. The motor will be on the passenger side up under the dash and will be held in with three screws.You are going to have to remove the motor and examine it.Watch your back,I won't do this job any more because of the way you have to double up.I'm thinking that the blower may have come apart and jammed.Many times you can get replacement blower fans at your local auto shop,or try your local wreckers for a good used one.Nissan will want way too much for this so try these sources first.You can apply direct battery voltage to the old fan to test it but be carefull,if its good it will try to torque out of your hand,and be sure you don't cross any of the wires,it can be a shocking experience( no pun intended) Take your time and good luck.

replace your blower motor resistor

bad fan blower. have you tried it on diffrent speeds? or see if the heat blows out?

I have a 2002 nissan Maxima. The AC controls only blow on level 4. No air or heat blows from level 1-3. What do I need to do to repair this problem?

It is under the glove compartment - get down there and look up and you will see a round thing. The fan may be good, it could be a relay (at least it was in my 94 maxima).

Relays are the big blue things to the right of the fuse (by passenger door - not under hood). You will have to remove a body panel to get them (a few screws). Not sure which one it the fan, but over the years my cruise control failed (see my post under 1994 maxima under gummydmilo - was a typo). My instrument panel failed. And the fan so I ended up replacing all the relays.

If you remove the fan, you can hook it up to 12 volts (the car battery), if and see if it spins - just be careful.
