When this goes on the truck misfires and tries to die. Usaully i can key the ignition in nuetral and the clicking stops and the truck starts and runs better

 

Sounds like a failing relay. No check engine light?

 

check engine light came on threw codes p0117 engine coolant temperature sensor circuit low voltage
p0705 trans range switch circuit
p0400 exhaust recirculation flow malfunction
p0743 tcc enable solenoid circuit electrical
p0443 evap purge solenoid valve control cicuit
p0452 fuel tank pressure sensor circuit low voltage

 

also have replaced 2 relays in that 3 relay block behind stereo. Only reason didnt replace the third one was because its the flasher relay

 

Replace the turn signal relay behind the radio.

 

why replace the flasher relay. Does it tie in with the trouble codes

 

I the noise doesn't bother you don't change it.

I no longer cared to hear the screeching coming from behind the radio.
