Chevrolet Repair: relay switch, fuel pumps, relay switch

Question
how do I chance a relay switch in a 1993 chevy half ton pickup ?

Answer
Hi Susie,

 There are many relay's on a 1993 chev half ton.  A relay is electro mechanical device that uses a low amperage signal to control a larger current flow device.  Relays are used everywhere from headlights to seat motors, fuel pumps, starters, horns etc.  What relay are you looking for?
