After reading through a few posts and not really finding any definitive answers, I thought I should just make a post and ask. I have a 98 lx470 that recently developed a loss of power or maybe a bad ground to the climate control unit. Both the temperature sensor for outside temp and the climate control will not start up when starting the car sometimes and Im not sure why its happening. I plan on going through the fuses and checking to see if one of the pins is not getting proper power to it. I had the head unit rebuilt to try and fix the problem but nothing changed. I also had the control module on the rear a/c unit checked and was told by the guy who rebuilt the climate control unit that the connections are all good. Does anyone have any suggestions on what else I should check or has anyone had this problem before?
