I just bought this lexus and i attempted to use the Ac and it only blew hot kinda semi cold air, is this because the system has to be recharged or somthing else?

A recharge is possible for the reason of A/C blowing hot air. Do you see the A/C light blinking when it is turned on? If so, it usually means there is something mechanically wrong with the A/C, particularly the compressor or the expansion valve (a common problem noted in the '92-'96 ES).

Definitely sounds like a refrigerant problem if no other warning lights exist.

No Warninh Lights, but i just found out i cant recharge this system myself because its an R12 System, which sucks lol, i would have to bring it to a shop, unless u guys know another way?

You could buy recharge kits and R-12 from eBay.

You can bring it into a qualified tech to recharge, have him retrofit or you can do a retrofit R12 subsitute yourself if you're mechanically inclined.

They do sell a kit at The Auoplace around the corner from me that allows me to retro fit my AC to conform to R-134a and it gives me a bunch of adapters n stuff, so ill try that

Hey i cant find the lower side pressure hose that i need to put the refridgerant in, do u guys know where u plug the hose in so that i can recharge the system, i think i found the High Side Hose Behind the Headlight but the instructions on the Reilling kit say i need to refill using the low side hose which i cant find????

flipside909

You plug in the hose on the fitting that looks like an oversized tire valve bung.

Hello. First post. Great forum

I've got a '93 ES 300 blowing warm air thru A/C
Was told by a mechanic to recharge it. I've gotten a can and a kit but having trouble finding the LOW valve. Could someone help in describing where to look or point it out on a picture? thanks

Low side fitting is near cylinder #1. Passenger side firewall. It took me a little while to find it on my car, but once you start looking near the firewall, it should be quite easy to spot.

Thanks George_Jet
I've actually seen that fitting before as I was searching for it. Isn't it a bit small though? the fitting seemed smaller than I've seen in my other car(mitsubishi), also LOW end.

GEORGE_JET

Sorry, I can't comment on the size of the fitting. My car was converted to R134 before I purchased it, so it has the quick disconnect adapters installed. Good luck

Thanks, I'll check it out tonight.

Dammit, I've just noticed that my system is R12!
Doesn't look like it's a DIY anymore, looks like I may have to take it to the dealer. Does anyone know how much they would charge for a recharge?
