need to locate the dual brake warning diode/resistor assembly and disconnect it .

Customer: replied 10 months ago.
Where is that?
Expert:  Kevin Bourcier replied 10 months ago.

i am trying to find it . I think it is just in the harness near the Instrument panel . Look for this connector near the left and side of the I/P and unplug it .

Customer: replied 10 months ago.
Ok I did disconnect that. It shows water in fuel and other information right? That gets information from the glow plug some how right? I dont know where to go from here.
Expert:  Kevin Bourcier replied 10 months ago.

with that disconnected the fuse still blows ?

Expert:  Kevin Bourcier replied 10 months ago.

go to the fuse panel under the hood . remove fuse " U " and look for the diode in this illustration and remove it also . see what happens then with fuse 18

Customer: replied 10 months ago.
it still blows. Ill do what you suggest.
Customer: replied 10 months ago.
There is no fuse "u"
Customer: replied 10 months ago.
I pulled out diode and the fuse still poped
Expert:  Kevin Bourcier replied 10 months ago.

see the diagram . the reference " O " , connector 212 is coming from under the dash and according to the under dash diagram is being supplied by fuse 18 .

Expert:  Kevin Bourcier replied 10 months ago.

you need to locate the dual brake , diode resistor behind the dash . I am trying to find it;s location .

Customer: replied 10 months ago.
When I find it whats next?
Expert:  Kevin Bourcier replied 10 months ago.

simply unplug it and see what happens with fuse #18 . your van has RWAL ? rear wheel antilock brakes , correct ?

Customer: replied 10 months ago.
Customer: replied 10 months ago.
I had the anti lock unit replaced. Could it have have caused a short some how?
Expert:  Kevin Bourcier replied 10 months ago.
