The bulb may be blown or weak,also check the flasher.
It has been my experience that when the blinker comes on but the lights don't blink there is one or more bulbs burned out. If that is not the case check the flasher.
When your 4X4 dash lights blink that is indicating a malfunction - could be just a sensor
change the bulb
Check for a bad ground
try replacing the blinker under the dash that little box that makes the blinker sound
blinker are you serious? BLINK !
If they turn on but don't blink, you probably need to replace the signal flasher relay.
Check all of your blinker lights. There are two in each tail light, one in each center signal, and one at the corner of each headlight, a total of 8 lights should blink when you have the flashers on. If a bulb is burnt out, it will increase the blink rate. Also, installing LED's in the tail lights will cause the blink rate to increase.
Wow ... I'll assume you mean your blinker lights don't blink. Most likely your bulb is burned out.
Check all of your turn signal bulbs. One of them may be burned out.
your blinker will turn on but not blink if a bulb has gone bad on that side or if your relay or fuse has gone bad
check your relay to the blinker. its wat makes it go on and off
