The diagnostic process for the heating and cooling is a very long and involved process and requires a couple of specialized diagnostic tools that you may not have.

Here are some of the easier things to physically check, which can be preventing the proper function of the seats:

Mechanical

• Seat track

• Climate controlled seat ducts

Electrical

• Climate controlled seat ducts
• Fuse(s)
• Circuitry
• Driver seat module (DSM)
• Lumbar control switch
• Memory set switch
• Power seat motor
• Seat control switch
• Seat fan motor
• Climate controlled seat module
• Climate controlled seat switch

Yes
1st pull tire from pass rear. 2 tie exhaust to pass side to help clear fuel pump access cover. 3 remove fuel lines loosen passenger tank strap and gain extra wire length . 4 remove access cover 8 mm bolts and work module out of tank. 5 replace pump assembly and 6 replace parts as removed.

Do you have a manual or electronic automatic temp. control ? What's not working , blower not blowing air ? most of the time the blower motor resistor is at fault.

check your for fan operation under normal operation if fan operate check for a AC on sigal at fan relay if not it may be a bad AC on switch on climat control panal

Does it work when you turn the A/C on? The fan always kicks on with the A/C, if it doesn't look for a blown fuse. Or possibly a fan motor burnt up. If it works with the A/C but doesn't when the engine is too warm, it is probably the temperature sensor.

When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

COULD BE BLOWER MOTOR RESISTOR OR BLOWER MOTOR CONTROL SWITCH IS FAULTY.

The fan motor resistor is most likely bad. It guages the temperature of the coolant and controls voltage levels to the fan. It acts as a switch, similar to a coolant temp sensor does in the engine. Good luck!

The blower motor might be bad,turn it on,high blower,and bump the blower motor body with the palm of your hand,if it starts to run,or tries to run,then replace the blower motor.

YOU HAVE A FAULTY MOTOR CONTROLLER.
