I have a 1995 chevrolet c2500 pickup. I wired a trailer recently and once done, turn signal no longer works on truck. Hazards work on truck and trailer, lights and brake and reverse on truck but no turn signal. I replaced the flasher but no luck. Flasher does not even click! I checked fuses I think.
Do you
have the same problem?

I tried 3 different new turn signal flashers, hazards work fine. Note that when I say I wired a trailer, the truck already had a four prong trailer plug on it so I did not wire the truck, just wired trailer lights on a trailer and connected 4 prong to the truck existing 4 prong.

Try disconnecting the trailer wiring to see if the turn signals works. Any fault in the wiring can cause the turn signals to stop working. Have you checeked the fuses?

I disconnected trailer wiring and fuses seem good. Again, hazards work, reverse and brake lights work. If I press down hard on hazard light button and hold, turn signal flasher clicks! And not sure why since there is a seperate hazard flasher and turn signal flasher

Check for voltage coming into turn signal switch purple wire(12volt), if ok activate turn signal, looking for voltage coming out of turn signal switch on either light blue or yellow (left signal). Or dark green/dark blue(right signal). If you have voltage on purple wire and nothing coming out on the mentioned wires, suspect turn sig. Switch

When you say turn signal switch, the entire arm with wipers and high beams? - High beams work and so do wipers, but I will check.

The turn signal swicth is located behind the steering wheel, the lever attaches to it, the switch has a harness on it that runs along the steering column, some disassembly will be required to gain accsess to harness for testing.
