I have a 2004 chevy silverado. The blinkers are not working, cruise sometimes works and the hazards dont work. I have tried a new flasher box and have tried replacing the actual blinker handle, they are still not working. They do work sometimes when it gets really warm in my truck. Any suggestions?

Hi there,

Both the hazard and the blinker flashers are located on the fuse panel. They pull straight out.

When both turn signals fail, the cause may be a blown fuse, a faulty flasher, a broken turn signal switch or a bad connection.

When you try the turn signals, do they light up and not blink?
-If so, probably the flasher unit.

When you try the turn signals, does nothing happen?
-Check the fuse

Let me know if the problem continues after replacing the flasher.

Try replacing the Flasher first before spending to much money for a possible simple fix. If it's not your flasher then it could be the turn signal leaver.
Ok, this may seem stupid, but that's what they did to the blazer. They set the flasher near the middle and under the center console behind the radio.

It's to the left of the radio right behind the dash. The hazard flasher and the turn signal flasher are side by side.  It right next to the Cig lighter behind the panel. They do mark the turn signal from the hazard flasher on the plastic behind them. Turn is on the right.

Good luck and hope this helps.

Hi Bill,I think before replacing anything else you should give that hazard switch a good workout.The switch doesn't get get used very often and the contacts get corroded and can upset the indicators.Good Luck.

Check all fuses. Use a test light to check if there is current to the rear bulbs when flashers engaged. If there is, then replace the burnt bulbs. Check for ground at the rear lights.
Do the front marker lights work when engaged??
