Hi t,
In 71 the relay is quite far forward…almost to the radio.
I'm not sure about 74.
Regards,
Alan

Wilcox has an excellent trouble shooting guide for wiper repair. I use it, makes for quick trouble shooting. last repair I made was to the override switch, had it in the wrong position. it's heck getting old LOL. T

I don't think the 74 will have a relay, that's a 68-72 item. Main things to check, make sure yellow wire at the wiper motor has 12 volts with key on. Make sure there is a ground wire to the body of the wiper motor and as stated above make sure the gauge bezel is grounded and not broken. The switch needs the ground because it grounds different terminals to make the wiper motor work.
