sjc6765 Posted October 19, 2007 Share Posted October 19, 2007 I have a 93 sc300,, the heat is acting up. It does not matter where I have the control set, sometimes on max cold,, I get full heat,, other times on max hot, I get nothing. The coolant temp is fine, no problems there, and the coolant level is good. Also the cabin temp probe is plugged in. I just do not know the system,, if it vaccuum controlled, or what. If anybody has any advice,, it would be appreciated. Thanks,, Steve. Quote Link to comment Share on other sites More sharing options...
