Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

Check to see if the mechanizm is siezed behind the handle that lifts up. this is quite common , also check the latches at the ends of the tailgate to see if they are not stuck in the unlatched position ,If they are retracted and won't come back out this confirms a sticky or siezed Mechanism.. WD 40 or someting simular to free up everything works well. good luck

Defrost is the default position. Is the control a autyomatic temperture control unit? ( you set the temp and select automatic) if it is the system is completely electronic. You push the buttons and the control still says defrost or can you select something else and the control shows it but it just keeps coming out the defrost? If the control changes and the air comes out the defrost anyway and the cheack engine light isn't on, then the problem can be blown fuses or an air door actoater not working. Does the dash emit a clicking sound? if it does with the covers off the bottom of the dash reach around touching the different pieces till you touch the idem that is clicking. this is an acutor motor, or blend door motor. they have gears in them that wear out and break the motors aren't repairable and you just replace the ofending motor. the door that is moves can be stuck. and may have to be freed up with blaster, WD40, or other rust buster till it moves easy. maybe after getting the door to move smoothly you can get the old motor to move the door wiithout having to install a new one.

The outside door handles on 95-97 Passats have a known problem. As they age, the pivot pin for the actuaring lever slides out of one of the support posts. This changes the geometry of the lever system so pulling on the handle does not open the door. The locking mechanism will work fine as will the interior door handle. The only cure is to replace the outside door handle.I have to replace my 95 Passat's Left front door handle about every 2 years due to this problem. Do not replace with a used handle as the problem will reoccur sooner. Replacement is easy; Remove the inner panel, carefully peel back the vapor barrior from the door by the outside door handle. Unplug the wire to the door hande and remove the Phillips head screw on the edge of the door that attaches the handle to the door. Slide the door handle toward the front of the door and gently pull it off. Reverse the process to replace it. Ensure the door handle wires are not pinched by the window mechanism and replace the inner door panel.
Remove the inner door panle by removing the door lock knob along with the screws around the front and back edge of the door panel. Remove the plasic cover on the armrest/door pull and carefully remove the wires from the outside mirror adjustment switch. Remove the 2 screws from under the armrest/door pull and pull the top of panel away from the door. Once the top of the panel is about 8 inches from the door it will lift out of the clips on the bottm of the door. Revese process to reinstall. Carefully glue the plastic vapor barrior in place before you replace the door panel.
