Question about 1999 Jeep Grand Cherokee
This problem could be several different issues.
The easy place to begin is the combination flasher unit. The combination flasher is located in a wire harness connector which is secured to the diagnostics splice block bracket outboard of the steering column opening underneath the instrument panel.
Check to make sure ALL of the turn signal bulbs are working. It is common on these models for sockets to burn and make intermittent connection. If one of the bulbs are not working it will not allow signals to operate.
Next would be a problem with the signal switch itself. The switch is part of an assembly called a multi function switch and is part of the turn signal lever assembly. Wiggling the turn signal lever will often reveal a problem.
Next is a problem with the BCM (body control module). This will be difficult to determine without the use of the proper computer scan tool. It may have set a code in the BCM.
I hope this helps you find the problem.
Thank you for using FixYa.

Sounds to me that the turn signal switch is bad and will have to be replaced. If you could wiggel it around and get them to work tells me that is wear the problem is.
