2004 Mitsubishi Diamante heat and Air blower motor.
Went drive my Mitsubishi the other evening, windsheild fooged up. Went to turn on defroster setting and I could not get any air movement. My first thought was a fuse. I have looked at both fuse blocks, passenger compartment and engine compartment and cannot see which fuse operates the blower motor. What should I do? Thanks!

Re: 2004 Mitsubishi Diamante heat and Air blower motor.
OK... First thing it may be a (relay switch) they are cheep and installed in sec. Ok now if you dont know what one looks like then go buy one ol' rilley or pep boys or auto zone are somthing . while your there buying the relay talk to these people most of the time they are good at supporting people . So you may ask "hey can you help me find where this part is located" . Ask about the fuse to, once you get someone out there to help you . One thing I know for sure is you did look in the correct spots for these fuses but let me tell you worst case. Would be your heater switch is out. They are expensive and are only found at the dealer. I would recommend looking on e-bay if this problem comes to this. oohh if you cant figer out how to put one of these in then find a friend that is rely good at installing car stereo's Im sure you will win this problem.

A/C Switch Assembly
The A/C switch assembly integrates the A/C request button, RECIRC request button and rear DEFOG button into a single assembly.
The A/C request button is enabled by the blower motor switch. The A/C switch assembly sends a reference signal to the blower motor switch. When the reference signal is grounded (blower motor switch turned ON) the A/C request button is enabled. The A/C request button is disabled when the blower motor switch is in the OFF position. When the A/C request button is activated (indicator ON), an A/C request signal is sent to the PCM. The A/C request button indicator can be toggled on and off when in the FLOOR/DEFROST or DEFROST mode, but an A/C request signal will be sent to the PCM regardless of the indicator status.
When the RECIRC request button is activated (indicator ON), the air inlet mode door actuator will drive to the recirculated air inlet position. When the RECIRC request button is deactivated (indicator OFF), the air inlet mode door actuator will drive to the fresh air inlet position. The RECIRC request button is disabled when in the FLOOR/DEFROST or DEFROST mode.
Do you have heat? Does the fan turn on? are you getting air from the defroster vents close to the windshield? If you have heat make sure the defrost control is working. I'd open the outside air vent and turn the blower on high speed. If there is no heat, the heater control valve is not working. Double check the radiator fluid tank, make sure you have enough fluid (antifreeze) Low fluid levels can reduce the hot water flow to the heater coil inside the car. If there
is no air flow through the defroster vents you may have a problem with the fan control, or the fan motor. Good luck.
First thing to check is the fuse. There will be one under the hood and another in the interior fuse box. The 2004 model does nt have a relay. If the fuse is good, you need to check to see if the blower motor is good. The motor is located under the glove compartment area of the dash, near the firewall. Disconnect the harness from the blower motor, and using jumper wires, apply voltage directly to the blower motor contacts. If the blower motor works, then the switch is bad. If the blower still does not work then the motor is bad.
