Question about 1999 Chevrolet K1500
OK in some cases the pins get dirty or corroded and pulling the relay in and out cleans the contacts. However I think that since you have had to do this a few times it might be worth while just taking a closer look at the relay. Remove the relay and remove the casing. Two things can happen to upset a relay a) the electrical contacts can become oxidised with the clicking/sparking as the current circuit is tripped - to fix this just insert a folded strip of sandpaper between the contacts to freshen up the metal contacts. b)((this is what I guess is happening to yours) check the circuit board and look at for dry solder joints or cracking around a particular pin. Anything like this just flux and resolder. A cracked joint can break a connection when the engine bay is hot (thermal expansion of the board) or just due to vibration. Good that you cornered the fault to the relay. Just fix the relay and I think your troubles are over, in this respect at least
