You may have a vacuum leak
On the passenger side of the vehicle, under the dash is the blower moter, there are two wires running from it, the one running to the resistor is mounted on the firewall. you remove the two screws with a star shaped screw driver, unplug the old resistor and plug in the new one...takes about 15 minutes.
What can happen when a blower motor resistor goes bad is that the motor will run and then suddenly stop running on a regular basis. Sometimes the blower fan will not turn on and cause the motor to overheat.
A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
The blower motor resistor is located under the front dash on the passenger side of the truck. It is a fairly simple job to replace...maybe 15 minutes.

Defective Blower Motor Resistor Pack. Replace it.
The Resistor is located on the outside of the blower motor. Have to remove the blower from under the glovebox to get to it. The Resistor is located on the outside of the blower motor. Have to remove the blower from under the glovebox to get to it.
A blower motor that only works on high is normally caused by a defective Blower Motor Resistor Pack. DRL, do not have a clue.
The blower resistor has failed.The blower resistor has failed.
The blower motor fan cools the resistor so the resistor is usually located close to the blower.
The a/c heater blower motor resister is located in the vehicle on the passengers side inside the housing next to the blower motor...............Remove the blower motor resistor wire harness connector.Remove the blower motor resistor screws.Remove the blower motor resistor.
# Locate the blower resistor under the right-side of the instrument panel # Disconnect the electrical connector from the blower motor resistor # Remove the blower motor resistor mounting screws and remove the resistor from the housing # Installation is the reverse of removal
The resistor is under the hood on the passenger side. It is installed under the wiper cowl, over the passenger side strut tower.
