Johnls400, You mention the caps in the climate control unit to be replaced to correct a nonfunctioning LCD. Mine works when it is 110 F in the car until the A/C cools the display down. How do I identify the caps in the circuit for the LCD is it obvious. Thanks for the information and your time. I was entertaining replacing the whole LCD display. Sincerely Kevin Mathews :)

as far as part # go, I was told this from a member who posted on the UK site: "Well Jason, welcome to our world. These are great cars and rarely fail, but when they do, you had better be prepared with a fat wallet. When the dealer gets done with you, that wallet won't be thinner, it'll be GONE! I can't help you with this problem, but I can with a potential future problem. You see, the 90-94 LS400s are notorious for the failure of the TEMP / TIME Climate Control LCD. They will begin to fail by showing a smudged black display. It will usually clear up on hot days, but the smudged black look will return when the display cools down. This will continue to worsen until it will always show the black smudged look no matter how hot it gets. The Lexus dealer wants approximately a ton of money to repair this problem. They replace the whole climate control unit itself. This unit has lots of electronics in it including the climate control computer itself. I am an electronics engineer so I decided to explore this problem and I found that the glass liquid crystal display itself is the part that fails, as opposed to an electronic component that drives the display. These displays are custom made for or by Lexus so you can't just go to the neighborhood Liquid Crystal Display store and by a replacement. Lexus won't sell them, they only sell the whole climate control unit. I decided to have some of these manufactured to my specifications. I ordered these with the widest temperature range that I could possibly order. Since these are custom made, it will take a while to get them and they are expensive but not nearly as expensive as going to Lexus. Anyway, I am expecting delivery of 5 engineering samples within the next few weeks. Once those are tested by me and I determine that they are acceptable, I will order at least 100 of them and offer them for sale to this forum at a very reasonable price. I have found the there is a difference in the displays between then left hand drive cars as opposed to the right hand drive cars. The ones I'm having manufactured are for left hand drive. It will require an adapter to use these on right hand drive cars. A daughter-board that will allow the use of the same display to be used on right-hand drives. I will design and offer these as well. Anyway, if you or anyone else out there is interested, please Email me and let me know. Jim Walker jimlwalker@sbcglobal.net" But I dont know if his way is going to be cheaper the 295?? Also this Mikado guy, can he repair them and keep the stock color and if so does this change the price? Or is the pirce the same even if you dont change the stock color?
