The a/c on 1992 Lexus Es300 was just recharged last month and just today the a/c was only throwing cold air out from the middle vents & the sides were warm air. It also doesnt get cold how it use too what could be the problem.?

beejayy1224,

If you have cold air from the center dash vents and warm from the side vents, its not going to cool the car down as you are used to.

The fact that one set of vents expells cold air and the others don't, says that the motor that opens and closes the side vent feed from the HVAC unit has stopped working. Either the door flapper is broken, the motor has seized/burned up, or the wiring to the motor has gone south.

The problem is that the motor parts are all under the dash and difficult to get to to fix. On a car this age, I would not be taking it to the dealership, as the cost may be astronomic. Find an independent mechanic who works on Camry's and get him to diagnose the problem and fix it. Be prepared to spend some bucks as it may prove to be a time consumming repair. Good Luck!

How much do those parts cost?

beejayy1224,

That's the wrong question. Why buy parts when you don't know what the cause of the problem is?

You may find that a wiring connector to the door motor has come undone, or the connector is corroded and just needs to be cleaned up. Its possible that a mouse has made a nest in the air box and its jamming the door open or closed.

As for the cost of the parts, once you know exactly what parts you need, if cost is a concern, find a wrecking yard that will let you take the parts off yourself and buy them for a fraction of the cost of new. Keep in mind that a Camry of that same generation may well use the same parts, which would make parts even cheaper to buy.

And if you don't have the expertise to do this kind of work yourself, find a good independent mechanic or a good backyard mechanic who has been in the backyard a while to do the work. Good Luck!
