I just came back from service shop. It was blower motor resistor, under the dash. Water got into it. So much for engine wash! It costed me $212! If I knew what was wrong, it would be %50 cheaper! It was very easy to replace, I watched the mechanic guy plug in the new part and charge me $100 for it................uh............Please don't wash your engine, if you don't know what you are doing!
