The low setting on my a/c would occasionally start blowing at medium speed then revert back to blowing at low speed from time to time, irregardless of whether it was on auto or manual. Meaning, even if I selected low speed, it would still blow at medium speed. Yesterday, it stopped reverting and now my fan runs no slower than medium speed all the time (unless switched off). My guess is it's the blower motor resistor, so I'd like to replace it. But I can't find any diagrams that show where it's located or how to replace it (I've checked the forums here, but couldn't glean enough to help).
Does anyone have experience replacing the blower motor resistor on a 90-92 LS400, and if so, can you explain the procedure? Would appreciate a diagram, too, if someone is kind enough to post one here.
Thanks in advance!
