i just have a problem with adjusting the power of the heat and cold air... the display shows up fine but it seems to be stuck in on speed... any ideas?

i know with the heat, it waits till the air is hot to blow air out, not sure about the ac, only had mine during the winter

o well i know that to be more specific it blows air like it's on 4 bars... so there is no difference between 4 and 1 they blow the same but i can change the heat... it just annoys me how i leave on the heat to keep my windows defrosted but my contacts get so dry...

hmm..broken blower? bad fuse? checked these already?

did you recently replace the climate control?

if your car is a 92-94

and you have a 95+ climate it will do that,

or the opposite
you car needs the climate from the correct series of years.

Yeah, I had that exact same problem when I replaced my 1992 climate control with a 1998 climate control. What I ended up doing was taking the working body of the 1992 climate control and swapping in the front (w/ working led screen) over. Something to do w/ the harness that does this.

Does it stay on stuck on the lowest speed...? If it does I'm willing to bet a large sum of money that its a Blower Resistor transistor, it has a funny name but thats what it may be... P/N-88750-24050 its only a good Lexus P/N because SC's have auto A/C and supra's dont.

At least yours doesn't try to turn your car over like mine does....I have the wiring book for the SC, I can probably find out the location of the blower resistor for you
