The problem
On certain diesel buses, the two-speed windshield wiper switch can cause the low speed wiper relay to chatter causing the windshield wiper motor to overheat.
The risk
When the windshield wiper motor overheats, it causes the 15 amp windshield wiper fuse to open protecting the circuit. This results in the loss of windshield wiper operation. Loss of visibility can increase the risk of a crash.
The fix
Dealers will replace the wiper switch. Owner notification began on february 17, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact optima bus at 1-316-779-7700.
