My 1993 Suburban has recently started making a clicking noise at start up and shut down. The noise is coming from below the glove box, but I have not found a way into that area. I think it is a air-handler issue related to vacuum, but cannot find any book or picture of that area. I spoke with a local Chevy parts man, but he would not print out his illustrated parts breakdown for the heater area. He said that there were three control devices in that area, but could not tell me how to get into the area, or anything else.
Any suggestions?
