Bought my son a 2003 WJ Friday

147K miles, 2WD, seems to be in VG condition as far as motor and transmission. A/C blows COLD (for now).

The left turn signal does not work. The right didn't either, but started working. I ordered a new turn signal switch to install. Also, the front right shock makes noise, so I will replace front shocks.

Because I'm lazy, what is the recommended oil?

Turn signal could be the flasher relay. There is also a circuit board in the tail lamp that could need replacing.

Yeah, I can get a relay locally, so thought I'd try the switch first. Didn't know about the circuit board in the tail lamp though.

To be honest, most of the time I've seen this it's the flasher relay. The circuit board is what the lamps plug into. For me, when my tail lamps didn't work it was the circuit board. When the turn signals didn't work it was the relay.

Does the Hazzard flashers work?

+1 on the relay being the issue. Most common and easiest of the likely causes to swap too.
4.0L I assume?

Synthetic is preferred by most of us. I just noticed wjjeeps says 10/30 for the HO. I've been using 5/30 in my WJs for decades and have not had issue.

Read the buyer's guide for what else to look for as issues...

I assumed if one side was still working, the relay might be OK. That's the other reason I went with switch first.

Change the relay first. If it doesn't fix then you could always return it. The stalk is probably a real PIB to.get out and to be honest I don't think I've ever seen many issues with those at least not in the forums I've been exploring.

If you get a chance, read up on the way that the relay fails and you'll see why we recommended changing it first.
There's an entire 25+ response thread on the topic with pics. Googling the issue returns a dozen more threads on this and other sites for the same conclusion.

I have read up on it, but I thought when the relay failed, both sides failed. My right turn signal still works.

When my relay failed it was the same thing.. only one side worked.

Verify the flasher is the problem...next time it flakes out on you, wiggle the flasher relay to see the behavior change. Before I re-floated the solder, I could bump that panel with my big toe while driving and it would work correctly.

Under a magnifying glass, i could easily see the solder cracks as in the images.
