Cool Wiper won't turn off

Jump in my 2000 4x4 LT Blazer with 103K on it. I turn the wipers on and push the place where it says Push to get wiper fluid on the windshield and nothing came out (No big thing there) BUT!!!!! My wipers won't turn off unless I put either one of my turn sigs on... Does this mean I have a short?

That would seem most likely. I'd have to look at a wiring diagram for the 2000 to try pointing out the most likely location for it. I'll see what I can find. In the meantime, I'm sure we have members here who have 2000s, and they might be able to pinpoint it for you.

More than likely it's in the Multi function switch, as they are known to go bad.

Thats the actual switch itself that you turn them on with. Another problem they had was the circuit board mounted on the motor itself. They get cold cracks in the solder joints. Simply remove the board and resolder them first. It's a known problem and needs to be done regardless and if it still acts up you can replace the switch.

So you are talking about the arm that comes out of the steering column correct? That needs to be replace? Or is located under the hood on the firewall? I live in AZ so "Cold" cracks, well I don't know about that, it really doesn't get that cold here. If replacing vs re-soldering, I will replace, it might cose more but takes away any soldering errors...What is the name of the board by the way and again is it located on the firewall?

Thanks

Its part of the wiper motor itself. It should come with the motor. Cold solder cracks have nothing to do with outside temperature. you know what a circuit board looks like I would think - when a component - wire, resistor, ect -is attached it is soldered to the board. If the solder isnt heated properly during assembly it can crack around the connection over time from vibration usually. All you have to do is reheat it and add a small amount of solder to fix it. All of those ECU's and BCM's or any of a dozen control units you have on your car or truck usually fail for this very reason and getting good at spotting this type of problem will save you big bucks over time. Anyway! Reman wiper motor will have updated board in it.

Sure I know about "Bad" soldering and what to look for. However all the soldering I have seen like that goes out well before a vech made in 2000. However I will take a look and see, but since the vech is a 2000 I will opt for a new motor only because of age and wear on other parts within the motor..might cost me a few bucks but just might save me a "Do it again" thing...I sure appricate your help in guilding me to the right area..

Thanks
