Yes.
Most likely turn signal flasher
If the turn signals on a car works but the hazard lights do not there may be a problem with the flasher switch. The flasher is located in the steering column, and a damaged unit can cause the lights to stop working.
either a bulb or the signal flasher relay located on the fuse panel usually opposite the hazard flasher relay
The cause for a turn signal flasher to keep clicking on a 1999 GMC Jimmy is a bad flasher unit. Replacing this with a new flasher unit should solve this problem.
The most likely cause of this problem is that the turn signal flasher is starting to "stick" and needs to be replaced. Depending on the mode year of the van, the flasher could be in different locations, but the most common spot is under the dash, near the steering column.
Short to ground.
Normally when your turn signal blinks very fast it means one of two things. Either you have a bulb that is blown or you have installed an incorrect Flasher Relay. Look an make sure all bulbs are functioning as they should be. If they are, then check to see if you have the correct Flasher Relay installed. If you do then replace the Flasher Relay.
The most likely cause is the turn signal flasher.
Okay, first turn the signal on. The look to see if the lights are blenking If the outside lights work then the little light in the dash is out. If the lights outside don't work you either wire problems or you need to replace the light socket. Don't forget to check the signal flasher relay.
Sounds like there is a problem with the turn signal switch but it could be another problem. First you need to see if the hazard light's work normally when turn signal is not on, if it does the the turn signal switch is the problem. If your hazard lights do not function when you turn the hazard light switch on, then it's a simple fuse or flasher canister that has gone bad and your hazard flasher is in the on position. If the Hazard light's have a bad fuse or flasher canister and is in the "ON" position it can cause the problem you describe.
Blown fuse or bad flasher unit. Often, cars use different flasher for the turn signals and the flasher, so it is possible for the hazards to work and not the turn signals.
Its probably a bad flasher or sometimes a bad bulb can cause that to happen.
