the heater use to not blow enough air so i tore it apart cleaned it it out and replaced the fan and it still would not blow hard enough.(when on high it felt like it was on low) now it wont blow at all and i went through the fuses.there is one labeled engine h that keeps blowing and i dont know where to go from here

 

Check your fan switch. Those like to melt and ground out, causing the exact problems you are describing.

 

so time to tear the dash apart

 

blower motor resistor searh 4crawlers page he has the fix

 

turned out that the fuse was god but not getting a good connection through boths ends on the fuse panel so i cleaned the terminals and the heater works again but still blows like its on low when i have it turned on high
