Just checked everything before hitting the road after the winter. Noticed window wipers not working unless I use the wiper washer push button. Checked fuse and it is okay. Kitchen Sink not working either with city water or water out of pump. Thought maybe air bubble but brought up front to level still no go. No leaks that I can see nor does pump run like I would think if there was water running continously.

You haven't given us much info on your MH. However the washer and the wiper operation may have different fuses. Assuming that is okay you may have a bad switch. If you have a multi meter see if you have voltage at the wiper motor. When you say the sink doesn't work, do you mean there is no water flow through it? If you are hooked to city water etc, and you have it by passing the tank fill you should have water at the sink. Could you have your valves incorrectly set?

It's not unheard of for the wiper switch to go bad. Use a meter and check wires on the back of the switch. A short jumper wire, with 2 male ends, can also be used to hook hot wire into switch to hot wire from switch to wiper motor.
On the sink, have you removed and cleaned out the aerator? It could be clogged. If it's O.K., if you have a water distribution manifold make sure the supply to sink is on.

2002 Tradewinds and I pulled on switch for wipers and then the outer ring of knob says slow and fast. I have water in the rest of sinks with city water and tank with pump. Thought maybe it was air in lines. Is the aeration for sinks for drain only or faucet also?

My Tradewinds has a filter inline with the sink on the back wall behind a bit of paneling. If you took it someplace to have it winterized then they may have removed the filter. If they didn't cap the line for the filter you would have water in the bay under the sink.
Do you have water at the drinking spout beside the kitchen faucet?

We never use the little faucet next to the kitchen sink but it does work so I purged the antifreeze from it also. It has an inline filter than is removable but since we never use it I don't ever replace the filter. The hot and cold water lines are connected separately from the little faucet. I don't think it is leaking everywhere since I think the water pump would just run non stop if there was a leak. Very strange I will take it for a spin and see if that fixes the problem. When you lift the handle to the faucet it doesn't turn the water pump on as it does with the bathroom sink. I suppose the faucet can go bad? is there a way to bleed the air out of the line?

Air in the line isn't the issue, water flow is. Air in the line won't stop flow, unless the pump is air-locked, but you say water does flow at the bath sink. Since hot and cold don't flow, it sounds like a shut off at a water manifold. Is water flowing through water heater to bath sink?

Unscrew the aerator then turn on the water. If it works your aerator is dirty. Start with the simple fix.

Have you ever used the wipers before? Make sure you only turn the inside knob (center) of the wiper switch. Not the outside. I didn't think mine worked either.

awolsmith · 04-21-2014, 05:07 PM

I did last year I believe. It's true that I couldn't remember which to turn if it was pushed in or out. Anybody got an idea if the switch could be bad? only place to find them is on ebay at $100 or so.

Before buying a new wiper switch, make sure it's bad by testing with multimeter and using a jumper to test wiper motor. If you need a new switch or wiper motor, you might check one of these places: RV Salvage/Surplus Yards (List) Updated 4/1/14 - RV Forums - myRVparks.com

I'm not sitting in my coach but I don't believe there is any pulling required. Don't you just turn the center section? I believe the outer ring is to adjust the timing of the intermittent feature. If the wipers work when you push the wash button the switch is probably fine. I will admit that I had the same problem when I first tried to turn mine on. It was smarter than I was.

Well turns out aerator on the faucet was extremely clogged and the wiper switch was fine, just didn't turn the inside knob on the wipers. So I took my lumps on this one but thanks for the info on the filter being so clogged it wouldn't let water thru. I learned something more about my Tradewinds MH today.
