Hi, My 1998 Suburban has had a couple of problems for a while. Here's the long and short: 1. the front blower seems to really be weak when pushing air out of the vents. Much weaker than it should be. I tried running 12V straight to the fan blower lead and no improvement. Also, I cleaned out the evap case (bugs, leaves, grime) and really cleaned up the evaporator too. No help. any suggestions? 2. the blower works fine when on any speed EXCEPT high. Sometimes in high it shuts off, or sometimes it doesn't start at all. When you bump the fan blower case under the passenger side dash, it will usually come on. I did some diagnostics on the wires, and found out that the red wire that comes from the blower relay (the relay only feeds the blower on high setting) is warm or hot to the touch on either side of a black connector. The black connector was also very hot!! when I disconnected the black connector and looked into either side (male and female), there was some evidence of melting of the plastic frame insde the connector. I just replaced the blower relay too. I'm wondering if I should basically just replace the black connector, or do I have a ground problem??
