i just installed a new head unit in my truck and i went to turn on the heater tonight when i left the house and nothing happen so i took my dash apart and checked all the connections to the back of the ***** and they where all good so then i checked my fuses and they where all good but i was wondering if anyone new what number the fuse would be for the heater fan/blower or if anyone else had any suggestions as to what else it might be any help would be appriciated!

 

Did the heater work before you installed the new head unit?

 

yeah it did it worked this morning when i used it and i went to go to the store and it would blow out any air hot or cold
