The problem may be low Freon, has it been pressure tested to see what the system pressures are? If not sure try adding some freon yourself using a a/c recharge kit available at most autoparts stores, just follow the instructions, if you are sure freon pressure is ok there may be a problem with the a/c clutch relay, it's located in the fuse box under the hood, all relays and fuses are marked on the inside of the cover, look for the 'MG/CL relay and try replacing it. Other than that there's not much more you can do yourself and it will require a professional using some specific special equipment to check the system.

Wha is the red triangle light with exclamation lexus

It's just the annoying light because you are due for service soon. Lexus programs all of their cars to "tell you" when service is due. To turn it off, hold down the odometer reset button and press the start engine button WITHOUT your foot on the brake. Keep holding the odometer button for about 5 seconds until you see the mileage flash. Then it will go off.

How to fits my chech light on my 1992 ls 400 lexus

fix 1992 lexus. posted to Acura. ok../....
the lamp is just a warning, it sits behind a sea of tests.!
what we all do, from 1988 to now is..... (USA)
we scan it. in your case this old car does not use modern scan tools
that car is too old here, 1996 is the year of smart OBD2 tools
but not all is lost. there are the blink codes
you insert a bent paper clip (metal) to the CHeck connector
aka: diagnostic jumper.
the CEL them flashes out codes. for what TEST is failing
first google hit.

do that, and report the codes.

with out obd2 means OBD1, in that link.
hackers do have scan tools for OBD1, but ill not go there.

2003 Lexus ES 300 the A/C light flashes and no cooling

The flashing light tells you there is a problem in the system.
A mechanic would check to see if the system is charged with freon then check the electrical circuit for the compressor.

Overdrive light flashing

Hi there. When the OD light keeps flashing it means that your vehicle speed sensor is bad and needs to be replaced. They should cost around $100. Good luck!

I bet money on the tranny speed sensor being the problem- I think NAPA has em for about $100 bucks or so, but that has been a while. Good luck
