Well, we drank the Lexus Koolaid again!! Our 93 sc300 was finally to far gone to remain practical. Monday we take delivery of a 07 is250. So I will be jumping forums. I just wanted to say thanks for all the help and support I have recieved here. Hope the new forum does as well.

My 93 sc300 is still acting up. This last winter, the heat went out. Turned out to be the heater control valve. I joined together the two vacum lines and had fantastic heat. Now it is time for some A/C and I am having cooling issues. I put the lines back (if someone has a photo/diaghram of the configuration to make sure I did it correctly) but both setups did nothing. Is there something else I need to do now to acheive cool air? Thanks

Spring is here, I unjoined the two vacum lines, but no cold air. Do I need to do something once the lines are unjoined & back in their original configuration? Thanks in advance.

It is nice to meet a "GOD" sometimes!! You hit the nail on the head. I joined the two lines together and had instant heat. When it is 29 degrees out side that is a beautiful thing. On to the next question. What does this mean now? Can the car run with this configuration with out any problems? What needs to be replaced and where can the part in question be found and for how much?

I agree with Bess, however, when you find the valve, just swap the 2 vacuum lines and voila, heat. However, do not forget to swap them again in the summer...............

I think I located the part in question. Is it about the size of a lighter with two hoses leading in to the bottom, and the electrical connection on top? If so, swapping the lines wont' do any damage?

Topped up coolant level, nothing. Swapped hoses, nothing. Still looking for options.

The car blows only cold air. Becasue I live in Dallas, spring is around the corner, and so is the warmth. So my question is what can I do as a quick fix (reasonable) to get heat. What can I ask a shop to do/check with out breaking the bank. Anything short of replacing the heater control valve. Sorry, 1993 sc300 120,000k.
