Q: i have a 90 lincoln towncar and the wipers dont work i replaced the motot and the switch on the coulmn and still dont work any ideas?

A: My '90 TC had various electrical problems and the trouble was traced to where the wiring harness plugs into the firewall. These connectors tend to corrode and begin to miss connections. Unplug the harness and do a serious cleaning of the connectors, male and female and see if that clears it up. In any case, you are due for a cleaning!
