2006 International 4300 washer fluid & wiper issues

I have a 24ft box truck and the washer fluid motor wasn't working when I press the button at the end of the turn signal. Also the intermittent wipers don't come on if the washer fluid button is pressed. I have changed out the washer fluid motor without any luck. Can someone walk me through what I need to check for please. I'm pretty mechanically inclined but a novice when looking for electrical issues.

 

Thanks for the feedback. I'll see if I can find one to switch out and try that.

 

Just a quick update. I checked out all the fuses and they tested good. After that, I took off the steering wheel housing and found the blue wire that runs from the turn signal housing had broken off and was hanging there. I removed the turn signal and cut the wire back about an 1/8" of an inch and jammed it into the pin where it broke off. Voila! It works. The intermittent wipers come on with the windshield washer and shoot washer fluid onto the windshield when you press in the washer fluid button. I have sourced a new turn signal and will install the new one once it comes in. But for now, I have washer fluid when I need it. The dealership wanted $250 for a new one. I found a new OEM one for $64 including shipping. So THANKS INDERJIT for all the help. I really appreciate it.
