[1970shortbed]

mine have been working fine now i have issues

they are setup with a relay and they used to come on/off on all by themself now they wont come one unless i take the cover off the relay and squeeze the contacts together

the temp gauge works fine and i have a new temp sending unit and replaced the relay with a new one to no avail

these were on here when i got the truck and i dont know much about them what elses is in line to make these things work

i have replaced a couple blown fuses but still not working

any ideas and thanks in advance


ps stupid question i see people all over the forum use the words nos what does this mean
