My 1994 was blowing hot air 5-11-01 so I took it to be checked out. They did a dye test and found no leaks. They recharged it and it worked ine for the next few weeks. I had a water pump go out and had it replaced as well as ading a manual fan switch. I had this done a few weeks ago and had not used the air since. I went to turn on the air tonight but all I got was hot air. Do you think getting the manual fan switch hooked up could have messed up the air? I went out and unhooked the battery for 10 minutes but that didn't help, in fact that made the service ride control light come on!, any idea's on the air as well as how to get the service ride control light off?.
