i have lost my stereo cig lighters heater and horn all at the same time for no apparent reason all fuses checked nothing a miss

 

Hmmm....Check the fuses again. Be sure too inspect the under the hood fuses. Sometimes they look fine until you actually pull them out of the fuse block.

How's the alternator performing? Supplying at least 13.5 - 14 volts?

 

i have checked all fuse individually 1 out at a time i have looked for the k174 relay which is supposed to be in left hand footwell and cant find it anywere not even on the other footwell and yes the alternator is fine looks like i have hit a brick wall lol

 

The radio and lighter share fuse link 2 (60 amp) under the hood. Did not see K174 on the schematic I looked at, what year is truck?
