Six problems related to turn signal switch have been reported for the 1997 Ford F-150. The most recently reported issues are listed below.
Multifunction switch malfunctions causing headlights to become inoperable while driving at night. Dealer has been notified.
On two separate occasions now, I have had the multi swwitch fail and need replacement. Both times Ford dealership in muskegon have replaced the part.
I have had to replace the multiswitch twice now. I am now on the third one already. As far as the front wheel hubs, the clearance is insufficient to allow for normal corrosion. Any front brake job requires that the hubs also be replaced as they are damaged when removed. All of my work was done at a Ford dealership.
Multi-function switch failed. Mjs.
Windshield wipers come on unexpectedly while switch is in off position. This is a safety problem because in the case of my father's ranger, the washer fluid would spray unexpectedly as well, thereby smearing the windshield and causing loss of visibility. Both our trucks were diagnosed with faulty multifunction switches. A recall for this part should be issued as there is a high number of the same complaints listed on this site for various Ford vehicles containing the same part.
Multi-functional turn signal would not work proplery: turn signal would disengage before consumer completed the turn. Dealer notified.
