wow great information thanks. i will give this a shot.
anyhow today i brought the lexus into the shop that im taking classes for to get my certificate. we hooked up the diagnostics and found out that the engine is running at perfect temperature. which led us to believe that the problem is within the gauge. we disconnected the temperature sensor and found out that the needle would not drop to c but one bar above... meanin gthat the gauge some how jumped a notch and reads inaccurate.. solution- replace temperature gauge?
any how the fans still dont kick on when ac is turned on. and i will have to trouble shoot the fan issue now with the information provided by obergc above. thanks your the man.
