I have been having problems with the turn signals on my Ford Probe GT. The turn signal fuse blows every couple of days during regular use. I brought it to a shop and they simply put in an automatic-resetting circuit breaker in place of the 15 amp fuse. This worked for a couple of weeks, but now they have stopped working again. I have tested the breaker with a multimeter and it is still good (no resistance across leads), but the lights do not come on anymore. I tested the flasher unit by swapping with another probe, but this did not make any difference. It still clicks with no lights coming on. Same with the hazards, clicks with no lights.
