hello, I have a friend who recently purchased a used 2000 Plymouth voyager, to make a long story short, the wipers didn't work, their mechanic narrowed it down to a problem with a vehicle computer, (I don't have to part number, she is supposed to give it to me tomarrow) they told her she could either get a new computer ($400) or they could install a bypass switch to control the wipers (which would have been cheaper) but she didn't want to compromise the stock look of the car so she went with a new computer, got the computer from the dealership, they used the old one to program it and when she took it to her mechanic, he installed and now the vehical is dead, doesn't turn over, no lights, nothing. I told her to just put the old one in so she could at least drive it, but she said she didn't get it back from the dealership, i told her to go back and try to get it. If anyone knows how she can fix her car please let me know. Thanks!
