my 1996 grand caravan

Given it is a 96 the problem is likely a worn-out blower motor. But there
are a few other possible causes. They are: blower relay - not likely;
resister pack for speed control - not likely but they do go bad and usually
burn up the connector as well. Switch on the dash - again not likely.
Leaving the blower.



Checking the blower. Pull the glove compartment door off so you can see
stuff easy. It snaps in place on the bottom and the side strands that stop
it from falling are simple to disconnect.



You'll see the wires going into the bottom of the blower housing and there
is a connector. Use a 12v test lamp or volt meter to see if you have 12v
when it is turned on. I like the test light with a needle end and a ground
wire so you can poke it through the insulation. If you have 12 volts it is
highly likely to be the blower motor unless the ground is intermittent. Very
unlikely.



You can remove the blower from the bottom. 3 screws as I recall.

when you get it down you'll notice it does not turn easily. That's the
problem!

The blower is a friction fit to the motor.

The motor is made not to be repaired but only replaced. If you have a vice,
hammer, and metal chisel you can pop it open.



It uses permanent magnets for the field and a standard armature and brushes.
It will be a mess inside. Once you get it apart inspect the brushes. If they
have plenty of length left and the wire connections are OK then clean it all
up. Us several drops of oil on the bushings. (I use 100% synthetic for most
motor bushings, Mobil-1 30w) They are porous (really!) so get oil all around
them but not on the copper armature contacts. When the motor is together use
the hammer and chisel to wedge/crimp it so it won't come apart.



Put it all together and test it by hooking to the connector before
installing back in the housing. You may get lucky. Or just buy a new one.
Recommended if you are not handy.



For what it is worth I did this last month on my 97 and 2 years back
replaced the resistor pack and connector. The blower works great now.
