It is possible if the flasher relay is going out or has gone bad.
The flasher is actually the hazard switch itself. If removed turn signals will not function. Just pop the old switch out and unplug it to replace if broken (if present and signal don't work).
The module in the dash is for the turn signals and hazard flashers. It is the flasher unit for both so since this occurs when using either system i suspect the module itself is faulty..it is a common part that fails on these.
The flasher unit is integral to the switch itself.
It's the orange light in the front headlights and the orange strip in the tail lights. The flasher itself is located in the dash behind the flasher switch itself.
check the turn signal flasher unit itself, believe turn and emergency flasher are the same on the camery. good luck
It's either in the wiring but more likely in the turn signal switch (in the steering column) itself.
The hazard switch itself is bad. The flasher module for the turn signal is built into it. Replace it yourself for 100 dollars(cost of part).
Try replacing the flasher. Inexpensive and quick/easy to do. If the turn signals will light up and only stay on, it's definitely the flasher, if not then the problem lies somewhere in the wiring, or the turn signal lever itself.
On the switch itself.
I assume it is the same on a 99 as a 2000. 2000 is right behind and is actually part of the flasher button itself.
check the flasher itself and the switch
Turn signal is on the left of the steering wheel its the wand thing that sticks out of the steering column that also has your lights and high beam controls. You flick the wand thing up or down for the turn signals and back for the high beams, and the hazard flasher is in the middle of the dash above your radio should be by itself between the vents
