I removed the glove box and the lower kick panel on the passenger side to check for the blower control unit but could not find it. I looked behind the glove box and all around but could not see it. I tried to listen for the clicking noise I here when moving the ignition switch still no luck. the clicking noise seems to be coming from the engine. I removed the blower motor and tested it and it worked just fine. I wanted to see if the brushes were good and eliminate the blower as the problem. I went ahead and installed a new ignition switch (not an easy job)and still the climate control does not work. I could not find the blower control unit behind the glove box? Thank you for all the help so far. I want to get the heat working its starting to get cold in NJ. Tomorrow there saying it will be 20 degrees. I would like to make this fix so if there are more suggestion please let me know.
