Weird turn signal issue!

Hi! I have a 2001 s10 w/s 2.2 5spd manual, I recently had the transmission guts replaced (2345 gears, clutch, slave cyl, and all the other goodies).
I got the truck back Friday, and today (Saturday) I'm having a weird issue.

The issue I'm having is when I turn the ignition on my front right turn signal comes on and stays on. It does not flash when I use the turn signal. However when I use the turn signal the right rear light comes on and stays lit.

When I use the left signal everything on the left works fine. I replaced the flasher/hazard relay behind the glove box to try and see if that was the problem but no luck. Due to work I won't be able to bring it back to the shop to have them look at it until Tuesday. Any ideas?

Thanks so much

There you go. :cry: LED's cause more problems than you can imagine. We continually have guys on here chasing weird problems with them. Try incandescent bulbs (original style) in all positions on the problem side. Get 3157LL not 3057LL. The low filament is nearly twice as bright on the 3157. LL is for Long Life which are better bulbs. Rockauto gets $2.02 a pair for them in 2 packs.
Autozone gets $10 - Amazon $12 - most places are $4-5 a pair. Ace hardware or Wallyworld.

Don't think you can make an old style 1157 work in a 2001 S10.

The four primary lighting grounds are one on each side of the inside of the radiator support and on the rear of an 01 there is a grounding junction block under each side on the inside of the frame. They have green caps and 4 or 5 wires into them. Then one wire from each has a short wire with an eyelet that is bolted to the inside of the frame. Look the wires over carefully as it's common for the wires to break inside the insulation. You'll feel a soft spot when flexing them.
