does the window work with the door open and the key on? there is a diode that can cause that. your model only has the fiber optics to the rocker switches so that probably is't the issue, i have seen the potentiometer for the dimmers develop an open and no amount of wiggling will cause it to work, you will need to remove the cluster and jump the terminals, and see if it send power to the lights. here is a picture of where you can put the jumper and see if it works, use a small piece of wire. as for the fan check the aux fan relay it may be defective,the voltage regulator will not cause these type issues,
