Hello, i have a problem with my turn signals ... they dont turn on... i want to mark that im turning but nope, the just dont start. everythings fine, all of the bulbs turn on... but my problem is that it dosnt matter if theyre on or off when i want to turn... nothing marks and the fuse is ok so if you could help me to know which maybe is the problema.. it would be nice thank you
oh i almost forgot, i have the front of the 95 the one with corner lights, small headlights and parking lights in the front bumper

 

You likely need to replace the flasher unit itself as they do go bad after a while. It looks like a silver cylinder around an inch or so wide, and will be located either in one of your fuse boxes or somewhere else under the dash depending on the make,model, and year of the truck.
They usually either stick open so the lights don't come on at all. Or stick closed so the lights come on but do not flash.

This unit is the source of the turn signal clicking sound that you would normally hear. So if you can remember about where the sound used to come from on your truck you will have a place to start looking for it.

Perhaps someone with your same year blazer can give an exact location of it on your truck if you have trouble locating it.

 

Hey bro!!! thanks! problem fixed hoho as soon as i read your answer i did it and that was exctly what was wrong thanks a lot...
however i saw when i put the new unit a directional arrow (right) was like turned on, i mark the right and everythings fine but when i want to mark the left the both arrows turn on like if i activated the hazzard ones i dont know why... mayb electrical problem of what? well thanks for everything

 

Try turning on the hazard lights and see if they flash properly. If they do then the wiring to the lights themselves should be ok. These trucks also tend to have a problem with the multi function switches going bad so yours may end up needing replacement. (check everything else first)

There is also a possibility that the bad flasher has blown a fuse. On my 01 blazer there is a separate fuse for left and right turn signals in the fuse box under the hood. As well as an overall fuse in the fusebox inside the truck. Your year truck may have a similar setup.
