My temp./clock is blacked out most of the time. But when the car is sitting in sun and temp. gets to 80+, the LED display works---nice and clear. Very strange! Why?

Asked by Lexmanken Jul 15, 2012 at 12:27 AM about the 1991 Lexus LS 400 RWD

Question type: Maintenance & Repair

As I mentioned above, I have a 1991 LS400 Lexus. The temp./clock is blacked out MOST of the time. However, recently I noticed that when the car is sitting outside in the sun, and the temp. inside the car is 80 or more, the temp./clock display looks and works fine---until the car cools down inside again! Very strange! Any idea(s) on why it is doing this? Is the display salvageable?

You're better off replacing it, for some reason these displays tend to give out when they age.

My LS400 is not running like a V8 should. For the first few years i've had the car it ran great. I use to fool around and drive fast, and when i hit the gas it picked up speed and roared like a V8 should, now it doesn't pick up the speed nor rev up like it used to. What could be the problem? What do i need to fix? 1 Answer
