Everyone should have a manual, and the library should have a professional shop manual available for copies in the reference section (FOR FREE)...read up and fix 'em like the pro's...! :) Dave
replace the combination switch on the turn signal stalk
The trunk
This varies with model year.
Bulbs or turn signal flasher, maybe even the switch.
it's normally under the dash.. turn on the turn signal and find the device that is clicking. That shoudl be the flasher unit/regulator/relay
More than likely the Flasher Relay is bad.
Sounds like you need a new flasher.
Turn signal flasher may be defective
Double-check me on this that the rear turn signal uses the brake bulb. That bulb is a 3057. See sources and related links below for more info.
The turn signal flasher is under the instrument panel to the left of the sterring colunm brace. (note I'm still looking for mine).
lever pulled out, having trouble getting the lever locked back in place
This is the turn signal bulb in the front bumper - passenger's side.
