Blower relay unit bad. common. Located on pass. side floorboard up by duct work. Hard to reach. Part is cheap. Looks like a little box with wires plugged in.

The first thing you need to do is check to see if the brake lights are working (lower lights not high mounted brake light), the park lock system gets power from the brake light circuit and will not release the shifter unless the brake pedal is pushed and the brake lights actually work.
if the radio is after market ...disconnect it and verify where the power and ground supplies are delivered..also if plugs are replaced make sure as to use "spark resistor" type plugs
Could have a DDS an PDS .depends on what RPO code yours has >
Outside Mirror Description and Operation (with RPO DL3)
Or
Outside Mirror Description and Operation (without RPO DL3)
Without
Heated Outside Rearview Mirror Operation
The REAR DEFOG relay controls the operation of the heated outside rearview mirrors. When rear window defogging is requested, the REAR DEFOG relay is energized and B+ is applied to the supply voltage circuit of the mirror heater element, located in the mirror face. A constant ground is also applied to the mirror face. Current will pass through the mirror heater element, warming the mirror, so long as the rear window defogger is commanded ON.
With
Heated Outside Rearview Mirror
The DDS and PDS control the activation of the mirror heaters. Upon receiving a serial data message indicating a request for heated mirrors, the DDS and PDS, will apply voltage to the mirror heater element supply voltage circuit. The mirror heaters will remain active until a new message is received indicating rear defogger is to be deactivated.
The power mirror system consists of the following components:
• Driver Door Switch (DDS)--An electronic control module with integrated switches and requires programming when replaced
• Passenger Door Switch (PDS)--An electronic control module with integrated switches, requires programming when replaced
• Power Mirror Direction Switch--Integrated into DDS and is a four position momentary switch that provides a signal input to the DDS for up, down, left/extend and right/retract with a mirror switch activation
• Mirror Select Switch--Integrated into DDS and is a three position switch that allows the operator to select the left or right mirror and also a neutral/fold position
• Mirror Extend/Retract Switch--Integrated into DDS and is a two position switch that allows the operator to select the mirror extend or mirror retract position
• Left Outside Power Mirror--Contains both the vertical and horizontal mirror motors
• Right Outside Power Mirror--Contains both the vertical and horizontal mirror motors
• Body Control Module--An electronic control module that requires programming when replaced, serves as the power mode master and is the main message handler
• Horizontal and Vertical Position Sensors, if equipped with memory mirrors--Supplied a 5-volt and low reference by the DDS/PDS and provide a variable voltage signal to the DDS/PDS that is proportional to mirror position
• Folding Mirror Motor, in each of the outside mirrors, if equipped with power fold mirrors--Provides extend and retract movements of the mirror and is serviced as a complete mirror assembly
Your best bet mite be to take to a qualified repair shop , i really don't think you'll be able to do anything with it.
Do you have wiring diagrams so you know which wires to test ,do you know how to do electrical testing ?
The Driver Door Switch (DDS) and Passenger Door Switch (PDS) supply voltage to the outside rearview mirror heater elements upon receipt of a serial data message from the HVAC module indicating that the rear defrost system is active. The door switch supplies B+ through the driver/passenger mirror heating element supply voltage circuit when a request is seen. Ground is applied through the driver/passenger mirror heating low reference circuit.
The switch is the thing on the dash with the knobs about 220 dollars. The switch(resistor) that controls the fan speed is under the dash on the far right under by the fan 20 dollars. I would check that power is getting to the fan or unplug and run jumper wires to the fan if it doesn't turn on the fan is bad 40 dollars. There is a blower motor relay under the hood in the black box by the battery or on the passenger side looking in the top it will tell you what relay and fuse is for what circuit. Sometimes they put a spare in there marked spare if not use an identical one from another circuit 14 dollars. If this helps please rate it thanks
The first thing I recommend is checking the fuse, then the electrical connections. If the fuse is good then I'd check the blower power wires, usually near the bottom of the glove box, making sure they are properly seating in their socket. You can further troubleshoot at this connection to see if voltage is getting to the blower motor. Use a DC volt meter, or a 12 volt tester light. The switch, relay, and blower resistor are other components in this circuit. Best of luck!
Check all fuses using a test light. If good, turn on fan and check for power at the blower motor connector. There all the wires there as each one is for different speed. If good, blower might be bad. If no power, check switch itself for continuity. Keep me informed.
