...As I was having AC/Heat problems,...I replaced the ignition s/w after testing all the other elec. items on that circuit... ...The AC worked for a day,...then back to the same old issue,...blowing #7 fuse... ...Now I have noticed that the new from the dealer s/w is quit hot to the touch,...as is the key when I remove it... ...Is the ig. s/w getting hot normal???...or is it possible that the mechanic could have,...not gotten the plug attached properly at the back of the s/w???...
