I am in need of some serious advise. I have a 1990 LS400. I have lost all power on my climate control and power mirrors, at the same time. My mechanic is a toyota certified mechanic. We can't figure it out. He checked everything that we can think of. Fuses, relays and the climate control unit itself. If anyone on this site can help I would GREATLY appreciate it.
Again, Thank you for taking the time to read this post.
