S-10 & Blazer1982-2005
The S-10 and Blazer was arguably the most versatile and accessorizable mid-size truck and SUV on the market.
Platform: S/T-series & GMT 330
I have an 89 s10. The blinkers do not turn on at all and when I turn on the hazars, the voltage drops from 12v to 5v. I put a new turn signal switch in it. Fuses are all good
Sounds like you have a short to ground. I would look for the obvious such as chaffed wires under the hood, wiring under car and what is missed a lot the trailer wiring harness.
