Blinkers

need some help.. i have a buick 89 lesabre & i have a blinker problem. the blinkers used to blink slow and kind of stutter, then they would stay light for a few second then start blinking again. recently they would not blink. so i would give the under side of the dash a smack left of the steering column and they would start blinking. well now that does not even help. they are dead no blinkers... is there a blinker relay?? a fuse ?? im hoping it is not a short in the wires. any help would be greatly appreciated

Blinker relay, located right about where you are hitting the dash. But it is located under the dash. There may be a plastic cover over the fuses and relay. The relay is about the diameter of a D size battery and about an inch long. Easy to change pull the old one out and press the new one in.

Thanks i will tear into that tonite. wish me luck ... electrical not my strong point..
even unplugging and plug simple stuff
