8-10 months ago, had to replace a/c compressor, orifice tube and accumalator on my caddy. then the evaporator core had to be changed. while gassing up, mechanic reset the computer in car. Hot air ever since. another mechanic here a few weeks ago hooked to computer and showed the ambient temperature inline switch was bad. GM part #25530598, and now I cant find a replacement because this part has been discontinued. Any ideas how I can get my a/c to work in this southern heat. Thanks
