1990 Dodge Ram Turn Signal Lever On Steering Collumn

If pushing down harder on switch helps then I would suspect faulty multi-function (turn signal) switch.

I can post replacement procedures if you would like. What kind of truck is this exactly? Also is it a tilt steering column or standard steering column?
