I recently swapped a fresh 3.0 into my b3000 because the old one blew up. Before everything worked fine, now everything works besides the wipers. The spray, or no of the wiper settings work but brights and blinker still work. Please help.

 

What YEAR B3000?

Probably just a fuse or relay but need the year to look at which ones

 

2001 Mazda B3000 and no fuses are bad

 

2001 wiring diagram below

Swap fuse 16 in cab fuse box with another 30amp fuse, or test it with OHM meter, just "looking" doesn't help you

There is no common Ground, Washer has its own as does wiper motor

The only other common points are the GEM Module behind Radio and the Multi-function switch(turn signal)

The wiper/washer switch has no direct connection to washer or wiper all "commands" go thru GEM

And, of course, make sure washer motor and wiper motor wires got plugged back in
