AC question
While driving up mountain pass on very hot day (104) my AC vents appeared to be blowing air that was less cool than normal. After car sat AC was blowing cold again. My question is: does SVX have override switch that shuts off AC compressor when engine/radiator coolant gets to a certain temperature? If not, what is explanation?
Thanks, sunvalleyray |

Did you have your windows or sunroof open?

Re: AC question
Mine strangly did this today also. I had my heater on this moring and after I left work I turn my a/c on and it was a little cool for 30 min straight. Then I let it sit for about ten min on high and it started blowing out ice cold and has since.

Re: AC question
Check your codes and make sure you don't have a evap temp sensor code or a mode door code.

Re: AC question
Mine showed up a code 14 on the select monitor, but I haven't looked in my FSM to find out where it is.

Re: AC question
I believe that is the evaporator temp sensor, depending on the model year it is either in the fins of the evap core or suspended very near it. It requires removal of the cooler box. If that is code 14, it will cause the exact symptoms you describe and will eventually cause the thing to not blow cold at all.

Yes, the evap sensor is easy to access once you remove the cooling unit that's behind the glovebox which has somewhere near 1,000 screws holding it together I believe the sensor is located inside the shiny alum foil tape. See pic.

Re: AC question
The one shown in that picture is the refrigerant temp sensor. The evaporator sensor is different, and if I recall correctly the 134a models had the sensor in the fins and the older ones had the resistor and it was placed in front of the evaporator. Funny, I was not aware of this end wrench article until just now, as when I replaced the sensor in one of my vehicles I put it back in the holder that suspended it in front of the evap and left the resistor installed. Whoops.
And P.S I always replace both. I never wanted to take that box out again.

Re: AC question
I looked the evap sensor up at work and it show it sits in front of the fins on the top and the refrigerant sensor is on the otherside on the bottom for a 1994. The evap sensor alone was $120 so i'm going to do this as my winter project.
