The heat gauge will sometimes go up toward 3/4 ways and then it will drop down to what I call normal about 1/4 ways on the gauge. I was told the only other thing it could be is the pcm. Does this sound right? A intake gasket or head gasket would not cause the fans to not kick on, Would it? The fan does not run with the A/C on. I am lost with this one. If any one knows anything else at all to check please reply.

You have three different posts going.
Which one do you want us to participate in??
WRT the fans, I know they will not come on if the low pressure switch on the A/C has kicked in due to low refrigerant. We had rear air in ours and the lines corroded and the refrigerant leaked out over a winter. Spring came, no AC. No fans either. Fixed the AC, charged it up and the fans started working again.
Are you certain that the AC is working?
