If it is the relay, yeah they wont work when removed and you can just replace it. I was thinking earlier, I dont think it is the relay, as there has to be power to the relay for it to work. What im saying is, if its switched off at the stalk, and there still on, it wont be the relay, it will either be a switch problem in the stalk or a wiring problem between the stalk and relay. Or a computer problem. Just want to say, not to scare you... I took a battery off a Iveco van not so long back to start another vehical. When i put it back on the window wipers and washer jets were constantly on. This was diagnosed as a ECU problem...
