97 Olds Bravada wipers and turn signals not working properly

The intermittent function for your wipers is controlled by the wiper control amplifier. This is an integral part of the wiper (combination) switch and is serviced only by replacing the switch assembly.

There are TSB's for this issue. I chased this issue for months on mine. Go find the TSB's, there's troubleshooting pointing out the faulty part. It could be, the brake light switch, the hazzard light switch itself, the multi-function switch. I had replaced all of these and still had the problem. Wiring that goes from the brake switch to up near the fender was shorting against the fender. I replaced the pigtail, problem fixed. Best bet to help you, is find the TSB's for this problem.

if the fuse is good and all the lights work(if you checked them when the hazards were working)then you need a signal flasher,the signals have a separate flasher and it looks like the hazard flasher.if you turn on the hazards and look for it under the dash then you know what the signal flasher looks like,it is located on the fuse panel of in that area.

The multifunction switch may be malfunctioning.Check and see if emergency flashers are working if they are then probably not the relay or fuse causing the turnsignals not to work but probably the switch.

possibly one side of your signal flasher is out turn on emergency flashers to locate one flasher then you can locate the other

The clicking noise is you concern ? I would replace the turnsignal switch or the hazzard switch.

Good Luck

IS THE FLASHER RELAY WORKING ?

I had the same thing - it also affects the 4 way flashers.  you'll end up replacing the entire control arm (turn signal lever)
Good luck!

The turns,hazards, high/ low headlamps, possibly cruise cont. and wipers, are all operated by the "multifunction switch". Replace it and you should be good to go. I hope this helps.

i can tell u this the multifuncion switch is in the steering colum signals,highbeam flash to pass and wipers chuck
