Question about Cars & Trucks
If the blower stays on medium or high, or stays on for more than five minutes, the blower relay is stuck. Replace the blower relay. (VERY common problem on these.) If the blower is low speed, and it only stays on for a minute or two, it is your automatic cabin air system (feature).

Rule of thumb...unless you get a better answer: look for a couple of wires on a small plate that is in the airflow of the fan on the heater/ac unit. The resistor pack is always air cooled by the fan.

in my 2004 grand caravan it's behind the glove box and left of the blower motor. disconnect the wires first then remove the 2 screws to pull out the resistor unit. First make sure you have removed the negative of your batterie. I had the same pm that prevented the blower motor to operate in any speed. I hope this will help

if fuses are good, check for power at blower motor, when truck is running and a/c on. the resistor and the switch provide ground, so the blue/white wire should have power, and the blue/black wire should have NO power, if it does have power, then most likely the resistor is bad. if it has no power and the motor doesnt run, the motor is bad.

Testimonial: "I will give that a try.. and post the results.."
hi for the blower motor staying on replace the resistor
check the connector make sure it is not corroded or melted
should have nothing to do with the remote start
this is an after market remote start
then the module could be feeding the blower motor
i have seen the after market modules do some strange things
hope this helps
