I have tried several relays from pep boys autozone etc. The relay either makes a weird grinding noise or doesn't work at all. I'm looking for someone who has successfully replaced this relay and which one they used. No local jnkyards have it. To the person who suggested the multifunction switch, what would that have to do wit the flasher relay or turn signal system? Please let me know...
The multifunction switch provides all the control circuitry for the hazard. If you have tried several flashers, and they are all on-spec for the car, then the problem lies in the MFS (MultiFunction Switch) itself.
Depending on the severity of the problem, something like electrical contact cleaner could fix the issue, but the best bet would be to find a replacement. You can get a new one from the dealer, from Glenn (convertiblesforever), or from your local junkyard. Although realize that if you get one that isn't new it may have a similar problem or may develop one sooner.
This is the circuitry for the main connector on the MFS, using a test light, you could inspect the inputs/outputs to ensure that the wires are wired appropriately and that there are no shorts.
There is also another plug on the other side of the MFS, but I do not have a pic/diagram of that with me. I will post one ASAP for you.
