The hazard switch on my truck will only flash the front passenger's turn signal and lights up the right turn indicator. Is this a faulty switch or relay? both front corner markers (194na) are burnt out if that matters.

tried to find the relay but can't seem to locate it. feels like the turn signal flasher is the one it's using. Is this true?

Got a 1992 F150

 

its not the flasher. must be the switch. how is that possible? is there a relay somewhere else other than behind the fuse box on the driver's side?

 

There are two flashers, the one for the turn signals is on the front (bottom) of the fuse panel under the dash, the one for the hazards is on the back (top) of the fuse panel under the dash directly opposite the one for the turn signals..

The signals and hazards will act weird if there are burned out bulbs, they need the load of the correct number of bulbs to operate properly...

So if you have replaced the bulbs and have changed out the flashers it is a good chance the multifunction switch (turn signal/wiper/speed control) could be your problem... but I would do some checking and be sure because they are proud of that switch.........

 

all the lights are working except the clear corner marker lights next to the headlights. I noticed they were burnt out when i was painting the trim. PIA to get them out since the bolts are rusted tight and the screw backs out of the light instead of the bolt coming off.

Are these corner marker lights supposed to flash with the hazards?

 

No, just the amber one under the headlight....

 

ok then all the lights are working :\ must be the switch then. Going to be pain to take the column apart. was going to take it apart when i replaced the gauge cluster but didn't have time lol. I bought some aftermarket led flashers on ebay and plan to put in some strobes so maybe I'll just leave it alone and use those for hazard lights :P
