was driving home yesterday after having a dead battery still can not find out what is draining it. but i can not get any heat out of the truck some times it will kick on but shuts off. i am going to check fuses in the morning to see of there are any bad ones

Check behind the fuse box for burnt wires.

Jim Lane's blower motor relay sticky has some great pics of what to look for.

 

also check the stickies for the relay upgrade, turns the fan at twice the cfm, takes the load off the fuse panel

 

I have had a couple of ignition switches do the same thing. My Jeep, my Ramcharger, and my 91 use the same switch and they all did it.
