1987 Gran Sport A/C water pump location

Postby rtgm1 » Sat May 25, 2019 10:38 pm

The A/C on my 1987 Gran Sport stopped working. I'm trying to located the water pump. Its not pumping water or doing anything else. Looking at the unit, I can see the discharge hose and probably where it goes to the thru hull. I can see the intake line but it goes toward the head and I can't seem to trace it down from there. Any idea where this thing is located? What else can I do to troubleshoot the unit?

I'm wondering if it could be the high pressure switch. Is there a way to bypass this to test it?
