pull the EFI fuse, the problem still haven't came back and I still have cold AC, lol, hope that works for you before spending money

I have had this problem also. I ahve a 1995 GS300 with about 80k miles on it.

I noticed that this only would happen upon very hot days (usually over 90 degrees) and also under hard acceleration.

I am wondering if the other guys here also are having this happen under these same conditions?? Please post a reply.

Also, I tried to track this down and did everything including cleaning every ground point in the car as well. I think the answer may be the a/c compressor, although, it works fine almost all of the time when the weather is under 90's degrees. It happens sporatically, so, its really a difficult problem to trace down.

Has anyone else had this problem and noticed that the weather was an issue? Anyone else actually fix the issue? I have done everything in regards to powering down the entire system, pulled the battery during the winter...but the problem always finds it way back.

This happens because of high pressure building up in the system on extreamly hot days so the pressure release valve automatically shuts the compressor off to prevent major damage to the system, thats why the A/C light blinks. a few things could cause this, 1. the condensor is clogged from dirt and/or debris, if so some degreaser should clean it up fine. next prob could be over charge, if the system has to much refrigerant it can also cause the compressor to shut dowm, for this issue you would have to take the car to an auto a/c tech for propper recharging.

I need help with a problem I'm having with my transmission. When I first start the car for the day (morning or evening) the transmission takes longer than normal shifting into drive (sometimes up to 20 seconds). Shifting into reverse is normal, with no problem. Only going into drive for the first time of the day. After it shifts into drive it works fine until till it is parked for an extended period. I have a 1993 GS300 with 280K on the miles. I changed the fluid with the recommended fluid Type T and the filter, thinking this would fix the problem but it has not fixed it. Would anyone have any ideas what this could be. Thank you for your time.

did you ever get this problem solved?? mine is doing the same thing
