hi , my ac worked fine for a good month or so after i bought the car but recently its been pulling some funny things.. my temperature for the outside air (the one that shows inside on the instrument cluster) went into the negatives! even tho it was like 60 outside. i noticed that because of thiis, my ac stopped working... so, i took the negative off of the battery for about 10 min and when i hooked it back up, it started working fine and started showing the right temp. .... it did this a couple of times already but recently when i tried the whole thing of taking of the negative and putting it back on, it didnt reset it! =( pls help
