Sorry for the long delay in answering again, as I still having to stop at library to use pc. I checked fuses again and the 10A fuse in passenger panel was blown. I replaced it and it did not blow again but still blows hot air. I can now hear compressor cycling. It sounds logical that since that fuse covers AC clutch, coolant control valve, aux coolant pump... that maybe the coolant control valve burned out and blew the fuse. It seems like I read somewhere that the coolant control valve is electronic.. what do you think shorod or any other users.. thanx it will be at least monday before I can get back to this..thanx again..
