Heater& a/c problem

[Gary prososki]

Sometime the heater works, Other days, it doesn't. Worked Yesterday. Today Nothing. I replaced the thermostat last month, because it wasn't getting up to proper temperature on the gauge.. Heat was working O.K. till this morning The heater hoses are hot .The temp gauge is normal. The radiator is full of coolant .I noticed the A/C clutch was cycling on and off. Tried all positions with selector switch A/C was still cycling on and off. It shouldn't be calling for compressor ,: until I select A/C or Defrost. Wonder if selector switch is bad.??? When the heat don't work it's ice cold. I get no response from the temperature blend selector when it's not producing heat @ all. Like it's not working just very cold air. Any suggestions. Thank You Gary.

Gary, use the Google search box near the top of every page, and search for " 2nd gen blend door " . You will find a lot of good info. I bet that's the problem.
