Hi I have a 2000 LS with the 3.9. I had overheating issues and replaced the thermostat, water pump, t housing and degas tank. No issues at all over heating now, most of which was the degas tank was cracked. Air works great but I have no heat. I checked the the #1 fuse in the underhood box and that is fine. I do notice that the passenger side doesnt blow the same temp as the drivers side. Would this lead me to believe its the DCCV control or heater valve is shot? Thanks
