First check the OVP relay, it's the one with the red top and a plastic cap. It has a fuse in it, take it out and replace it with a new one. The temp sensor is at the back of the engine by the oil filter the last one with two wires connected to it on the intake intake manifold. It has two post/poles and is usually green in color but may be black too. This controls the computer telling it if your car is hot or cold to turn on the cold start valve. Also, make sure your wiring is not cracked and check all the connecting on the cold start valve.

is a German Tank
the OVP relay lies behind the battery....remove the water shield (black plastic behind battery) there you will find the OVP relay with said fuse.

Check the motor. It is in the left side of the trunk and runs a cable that goes up through the pillar. You should see the white knob turning when the switch is activated. If it turns but the sunroof does not move then the cable is probably disconnected or broken. It's a quirky little device, but self explanatory. It has a timing assembly inside it so try not to turn the knob and get it out of sequence.
