2000 Astro Wiper Motor Problem

It seems like as soon as you get one thing fixed, something else quits!

Frnt Wipers/washer quit. Checked/swapped 25amp fuse under dash (it looked fine). Looked at Autozone to price a motor and I see where there is also some kind of "module" or "board" that can also be replaced.

Is there anything else I should try before swapping out the wiper motor?

Thanks for your help!

To test for the infamous broken solder joint- turn on wipers with ignition on- engine off- then walk around front and wiggle the connector to the wiper motor- if wipers start working you can either go buy the module- or do what I do- heat up the solder gun and just touch each solder joint where the connectors attach to the circuit board- (you have to unbolt the 3 screws to remove the wiper motor cover and expose the circuit board or module) This joint flexes with every swipe of the wiper blades- and is highly prone to eventualyy break the solder joints-- I've done about 6 this way- mostly on C/K trucks- but my van was the first one I saw it on.....

I didn't get anything to happen with the key on and wiggling the connection. I disconnected the plug and tested to be sure there is fire making it to there. The circuit board was covered in red grease so I cleaned it up and put it back together. Still nothing. I bulled the wipers across the windshield (oops!) and now they won't go back down. It's not supposed to rain till Saturday so I'm good through the trip to work tomorrow. I guess the next thing is to buy a circuit board? Guess I could replace that and then go to a motor if that doesn't work?

Thanks!
