Any ideas? I haven't heard of these failing. Does anybody know if its maybe a fuse blown and if so which one? I looked in the owners manual and I'm not sure. I also have a block heater cord that had been cut and someone told me that they cut the end off when the block heater fails. I checked the oms between the two leads and it read 29.7oms. Someone told me that it should be closer to 0oms so if anyone could comment on that too.
Thanks,
Dan
Figured it out... I had my wife listen for the wiper fluid motor to turn on and she could hear it when I pressed the button. Followed the hoses and found one was kinked just under the plastic cover below the windshield.
I too had a problem with my windshield washer not working (of course he rear washer would work). I pulled the battery and washer resevior, inspected the pump, it would only pump the rear not the front windshield. I replaced the pump and still the unit would not operate.
I took it to my buddy who is a master mechanic and he found that one of the relays in the relay box under he hood had failed. He replaced both and they work perfectly. Lesson learned check the relays after the fuses and make sure that they are good before you go any further. When you depress the wash switch you will hear a click if the relay is good.
I had the same problem. I could here the pump but no spray. Pulled right headlight to get to pump. Pulled out pump and foung it clogged with what I would describe as blue gum. Cleaned it off and re-installed. Good to go.
When I got my truck in March one of the outlet was giving me problems.
So I remove the the inlet grill just below the glass and unhooked the
hose and got a nice squirt. I thin just removed the old nozzle and
put a now on it it's place. Works nice now. Lesson is if you have a
plugged nozzle unhook the hose and run to clear out any dirt in the line.
On the block heater 0 ohms would be too low 10-24 Ohms
@ 10 Ohms you have about 1440 watts and @ 24 Ohms you
would only have 600 watts Where 3 Ohms would give you 4800watts
and the amperage would be 40Amp more that a house plug can handle
The one at 10 or 11 Ohms would be you best bet at about 1440 Watt
and 12 Amp.
You can replace a bad plug with a replacement kit. Like this. Ford 7.3 6.0 6.4 6.7 L Powerstroke Diesel Block Heater Cord F350 F250 Excursion | eBay
But you need to test the element to see what the resistance is and
also check one of the leads to the block on the Meg Ohm range that
should show like an open circuit otherwise you will have current leaking
to ground by way of the coolant and that is not good. If plugged
into a GFCI it will trip to keep you from getting shocked and that could kill
someone. That would not be good.
