You need to replace the blower motor .It is drawing too much amperage,and burning out the resister.

There is a short circuit on the B+ power circuit for the blower motor ! Your best bet would be to take your vehicle to a qualified repair shop ! Finding electrical shorts can be tough ,even for seasoned tech > There are videos on youtube on finding short circuits an basic electrical trouble shooting , how to read a wiring diagram !

I changed blower motor & resistor. I to replace motor and keeps blowing 2 15 amp fuses in box under hood.


well the blower is not shorted.
there can be a short anywhere from the switch to the blower.
did you look at the operators guide first to see if the fuse size is correct. man blower suck 13 amps. or more.
changed? does that mean a new blower or used?????

a blower can be hand tested and hot wired
i do that with 2 things.
a jumper clip with 20amp inline fuse and 16gage wire.
and my ammeter connected. (clamp)
if the blower works and does not suck too much current its ok.
its just a simple DC brush motor.
and can blow and still be bad, see why? ( armature segment shorts)
but sounds to me like harness shorts.
if the fuse blows with no resistor and no blower, its a harness short.
i dont have fuse box spec, so you will have to find that.

OMG, i looked in the online fsm.
what wierd car..... this blower.
its got 2 fuses for that blower,
EB5 and EB6 wired in parallel,, what joke that is.
the short must be on the blue-white wire (ONLY)
if at all.

here is the proof.
amazing how books work. huh?

When i cut the car off the air blower remained on,but the gauge displayed that the air was off.I even disconnected the battery cable and the blower went off and came back on 3 seconds later while cable was...


I've answered the same question from you twice already. Reposting it will not get a different answer.
First, there is no. Possible. Way. That the fan will operate. Unless there are unicorns living in your car magically powering the blower motor, there is no way it will be on with the battery disconnected. It's not possible.

The resistor block controls blower speed by reducing the amount of voltage supplied to the blower motor. The higher the speed you select, the less voltage is dropped, resulting in more current getting to the motor, resulting in a faster spinning fan. If the power feed side is shorted to the output side, the blower motor will operate constantly. The circuit that feeds the motor can also be directly shorted to the motor, completely bypassing the resistor. Unless you know how to use a DVOM, you will not be able to diagnose this on your own.

A/c blower stays on while the car is off and is draining the battery.


Seems like you have an important short circuit. Blower is supposed to be cut off when car is shut down. I have seen blower switches melt, from excessive use of high speed blower, shorting the contacts, and staying on permanently.
