Message: [QUOTE="doo dah, post: 1551154, member: 22536"] I have searched but none of the posts I found had the same issues, or at least description of issues, that I have. Last summer my truck would blow cold air and then hot, it wasn't cyclical rather once it went hot it would not blow cold sometimes for days. Did some research and bought the new evap temp sensor and plugged it in without removing the old one. Blew frigid cold for about 15 minutes then no air coming from the vents and what felt like cold air coming from the floor vents. Turn a/c off and leave vents on and eventually air started coming from the vents, cold at first eventually becoming warm. I figured the sensor was freezing the coil and the initial cool air was just outside air blowing over the coils so I got a recharge kit and system was a little low on pressure so added a can. Tried running a/c again and same thing happened so I unplugged the new sensor and plugged the old one back in and we had cold air for about a 3 hour drive. On the return trip home, no a/c just outside air through the vents for a few hours until we were 20 minutes from home and then started getting cold air. I'm at a loss and ready to go to a shop since this doesn't sound like a blend door or evap sensor issue, any suggestions? Thanks! [/QUOTE]
