No Heat

Post by crazy4saabs » Thu Nov 24, 2011 8:31 pm

I am experiencing intermittent heat from my 99 9-3 convertible cabin air system. It has manual, not climate control. I replaced the thermostat about six months ago, and just recently replaced the heater hoses that feed the heater core. I thought the heater core was blocked but I just flushed it with clear water. That has not solved the problem. Sometimes the heat does work, but usually only for a few minutes before it cuts out. I'm thinking it must be some kind of control problem, but definitely looking for help. The temperature guage seems to be reading accurately, with needle just a hair below 9 o'clock postion.
