I have a 86 420sel that keep on blowing the blower fan fuse. I replaced the blower fan motor with a new unit. It does this when the fan is on high. Also, I've been having problem with the AC cutting out. I tracked it to problem with the push button unit. There is no ground signal. Can there be high resistance in the PBU causing the fuse to blow and the AC to work intermittently?


Thanks,

John
