Ok I have an issue that's been going on a while now. To begin with it all started this winter when I forgot the truck idling with the heat on high for about an hour and a half. The keys were hot to the touch when I shut it off and it was really hot inside. Ever since then it randomly shows ac off on the cluster and the temp sensor stops working. Well first guess was replace the temp sensor, didn't change anything. The more time has went on the less the ac works, temp sensor always quits reading when the air goes off. I even cut out the plug for the sensor and just wired straight in and no change. I can disconnect the battery to allow the truck to reset and when I first start it the AC works fine, a lil driving or hit a bump and it goes off. Has me stumped. Any ideas or input would be appreciated. I traced all the way to the fuse box earlier and couldn't find any shorts, etc
