bermuda1978

Everything else functions normally....defrosters....temperature settings...etc. The fan just switches itself from low speed to high speed and back to low speed very erratically on its own. No rhyme or reason.

Thanks for your reply. I do not have a factory installed phone.

I have a 1996 LS400 and the A/C fan speed is acting crazy. The fan can be set to any speed and it will start to go from high speed to low speed at random by itself. It's rather annoying...it acts like it's possesed. I've tried to select "auto" and let it self adjust, but the fan still acts crazy in that mode as well. Anybody have any thoughts, or seen this before? Thanks!
