...fix it, can you help? I've been using my brothers jeep for the last few weeks until he gets back in town, he knows cause he said ok, but the thing is, yesterday and today i noticed that the wiper in the back doesnt work when I turn the thing "on". i may be really dumb with car stuff, but i know for sure its the right button thing to push, cause i've used it like once a day cause the back window gets really gross when you drive fast and you need to wipe them once in a while. Anyone know why it stopped working all of a sudden? Do i need to take it into the shop and if yes, how much you think this will cost?? k thanks!!
