1990 f150 lariat xlt 4.9 wipers are intermittent
Just bought this truck and the wipers aren't working properly. They work on high and low and delay but are intermittent. Did lots of reading ( mostly on here) with everything pointing towards the governor. Pulled mine out found one broken solder point. Resoldered this connection and reinstalled. Now the wipers only work on high and are intermittent. What's my next step? Any info would be helpful and appreciated.

You probably need a new wiper motor. There are contacts inside for controlling when the wipers 'park' and if they wear out the function gets wonky like you describe. You can check them by popping the black plastic cover off, might be able to clean them to keep it going for a little while longer too.

A little off topic but what kind of switch would I need to wire the high and fluid to a single switch. I'm mud racing and it gets a little hard pushing buttons and trying to stay on the track. My wipers actually come on and work until i hit a few bumps and they will get stuck then start again.
