If it is controlled off of this board which relay is it?

Thanks,

Provided your truck has a similar A&C unit, the upper left relay marked P1NO12N is the rear wiper (see the above picture). In the picture the front wiper relay is circled.

Here's a link to a thread where KJK swapped the relays and fixed his front. His rear stopped working.

Good luck.
