We rebuild your 1990-1994 Lexus LS400 climate control unit. During the repair process, we install a brand new LCD screen and high-quality bulbs behind the buttons. LED colored screen and buttons are available for an additional cost.

Tanin Auto Electronix began rebuilding and selling the LS400 automatic climate control units back in 2012, it was one of our first repairs. Similar to the SC300 and SC400 we quickly manufactured and started branding our new Tanin Electronix LCD screens for use in our repairs and to sell to the consumer. We required the new LCD screens to have high heat tolerance. The problem with the original screens is they would fade to black or start to bleed.  The bleeding is common from LCD (liquid crystal displays) from the 80’s and 1990’s. There actually is a liquid based component inside the screen. Over time the glass and other components succumb to heat and start to turn black or develop a yellow haze.

Our rebuild service replaces all of the lighting inside the climate control as well as the LCD glass. These are the only two issues common with the 1990 – 1994 LS400 climate control. These were very robust units and all the other electronic elements in the car also did not suffer any failures. Luckily this is an easy repair for us and we have rebuild and sold hundreds and hundreds of these units for LS400 drivers across the globe.

We install one brand new LCD screen protector if your climate control needs it. Separate from the LCD screen itself, we had customers asking if we create a screen protector to prevent blotchy, foggy, scratched, and worn areas on the actual plastic screen covering the display. We found that the only solution was to pay for a $300+ replacement faceplate. We then designed and manufactured this plastic lens as a cost-effective and simple solution to offer our customers. Your climate control will return with a crystal clear viewing port.

Overseas the LS400 was sold as the Toyota Celsior in a RHD (right hand drive) model. This means everything electronically was flipped 180 degrees to accommodate the driver on the right hand side. Unfortunately this also meant the LCD screen was flipped so our standard left hand drive LCD could not be used. Luckily we sourced right hand drive LCD panels so we are equipped to repair these units as well.  While not as popular compared to the SC300 and SC400 we can also change the colors inside this climate control. The factory color is a green tint and ours will look the same as original.

We also sell complete HVAC units:

This repair service also applies to RHD models of the 1990-1994 Lexus LS400 and Toyota Celsior. We do not have screens for the climate controls with the “small” LCD screens or rear climate controls. There is an additional $100 charge for the right-hand drive models – you can select this option before adding to your cart.
