1997 Volkswagen GTI

My name is Stephanie I have a 1997 VW Golf Gti vr6. Over the process of the last few days we had to tear the dash out and everything to replace the Heater Core. When putting the car back together we found that there was a wire that was not connected to anything but procceded to put the dash back together. We looked at the back of the heat controls and everything looked to be plugged in correct. When starting up the car we realized that the switch where you turn the heat on wasnt turning the heat on. The car warms up and runs okay but where you turn the heat on to the 1, 2, 3, 4 or whatever doesnt cause the heat to come on. I am not sure if it has something to do with the wire we didnt hook back up to something or the block fuse (relay fuse I believe its called) but before getting another fuse from a VW dealer, or tearing the dash back out I wanted to get some advise.

The fan is not blowing?

What color is the wire?

Using a test light, you can check for power at the fan switch and at the resistor pack (by the actual fan).

No power at the switch, then re-check the fuses. If you have power at the switch but not at the resistor pack, find the break in the wire(s).

The fan motor GROUND wire needs to be attached at the bottom right of the dash / chassis ground.

Too many variables to solve via a keyboard.
