Greetings!
After a minor accident, my AC and heater stopped working. My mechanic replaced a couple of AC parts and huzzah! I had plenty of cold arctic air! Then the seasons changed and I tried to turn on the heater. The fan works fine, but only cold air came out. I took the car (94 ls400) back to the shop and Randy tried checking out some cables, etc. He said everything seemed to be working ok, except no heat, but he couldn't be sure of the cause because he needed to investigate further but had to leave work at noon that day. He suspected the heater core might be bad and asked me to bring the car back the next day for more tests.
As I drove home, dreading the cost of replacing the heater core, I felt something coming out of the dash... HEAT! And lots of it! Problem solved, I thought. Wrong.
The AC no longer blows cold air, only hot. And I can't get warm air. Only really, really hot air.
I suspect the Randy the Mechanic flipped the door from ac to heat while he was investigating. Is there some sort of control that would mix cold and hot air to produce warm air?
Any and all replies will be greatly appreciated. Thank in advance! :D
