1994 s320 erratic hazard lights
 

hi all, what a good site this is,

have just bought an s 320 1994, had an inspection and all was well, this morning after a day of problem free driving, i find the hazard lights flashing on and off very quilckly, quicker than usual hazard warning flashes, no alarm problems, drives ok but hazard flash constantly !!! was told it could be the preasure clean the day before i bought the car and then a night of constant rain could have caused water ingress in the electrics, only way to stop the flashing is to pull the fuse, and the alarn still works fine with fuse out. any thoughts

thanks
