As I live in Phoenix my Catalina is always hot after being in the sun. If I run the blower on high for any length of time the fuse on the back of the alternator completely fries to the case. Inside the case is a 30 amp fuse. How can I correct the system so that I can continually run the blower on high. The blower motor was replaced and is fairly new and I only have the problem when it is run on the high setting. I do have a new blower switch but have not yet installed it. Any help would be greatly appreciated as I use this car a lot and with the heat it is mighty uncomfortable. Thanks CW
