'94 Sierra windshield wipers

I purchased this vehicle several years ago and found that it had
windshield wipers with a mind of their own. The wipers would either
not turn on (usually when it was warm outside) but has now become a
safety issue since it has died on my while driving in the rain at
night (they have come back on since). I am now ready to solve the
problem, I have searched this site and what appears to be an issue
with the wiper delay circuit board. I have found in the LMC catalog
that I can get the circuit board for about $40 if this is the cure
then how hard is it to get to and replace?

Item#: RAY49700PB at NAPA....$20.49.
