SamHouston Posted September 15, 2005 Share Posted September 15, 2005 Hi all, I'm new to this forum. I'm looking at a 91 LS400. I checked carpoint.com and they reported this expensive problem: <<<< Heating & Air Conditioning A periodic problem on this vehicle is failure of the Air Conditioning (A/C) Compressor.The cost to repair the A/C Compressor is estimated at $781.00 for parts and $143.00 for labor. >>>>> Question for 91 owners: Is the above true? How often does the compressor fail? Any other problems I should look out for? Many thanks for sharing your experience.

1990LS400 Posted September 15, 2005 Share Posted September 15, 2005 The compressor on my 90 LS was replaced in about 1992. I think the replacement was supposedly an improved version and it lasted until about 2001 or 2002 when I had the compressor replaced and the system converted to R-134a. The system worked very well on R-134a - I once ran it for about an hour on a 100 degree day while parked in KC Royals stadium parking log and it could have frozen the four of us out of the car - the coolant temperature gauge never rose above normal while doing this. The current owner of the car said the system has a minor leak and he has to top it up about once a year - probably not bad for a 15 1/2 year old car.

daffy Posted September 15, 2005 Share Posted September 15, 2005 Hi SamHouston, I have a 1991 Ls400 with over 420,000 kilometers(about 260,000 miles) and my air conditioning is still working. I have never had it topped up or even looked at. So my experience with Lexus air conditioning has been top notch!! Great car! Daffy :D Quote Link to comment Share on other sites More sharing options...
sha4000 Posted September 15, 2005 Share Posted September 15, 2005 i think this is problem on the early model ls there was a thread somewhere on the forum discussing it, when i had my 91ls the compressor failed at about 160k but that was in 2003 Quote Link to comment Share on other sites More sharing options...
