My turn signals seems to have a mind of their
own. On hot days, it just refuses to work.

All other electricals appears to be fine. The hazard lights also work fine.

Any ideas?

The first thing to do is replace the fuse, it might look good to the naked eye but replace it anyway, they can corrode and/or "burn" on the ends. The fuse for the turn signals is different than the fuse for the hazard lights.
let us know if this helps.

Thanks MB Medic...

The turn signals worked fine this morning (6:00AM) when I left for work. I parked the car in the ususal spot out in the sun, and when I wnet out around 9:00 to buy some fuses, it is no longer working. I picked up the fuses replaced ALL of them, and still no dice with the turn signals.

What is my next step?

You may want to replace the flasher unit.

Believe it or not, but I can not find the flasher unit. That was the first thing I thought of, but after 45 minutes or so under the dash, I figured there must not be a flasher on the car.

Where is the flasher unit?

It is in the fuse box in the last slot closest to the firewall. It does not look like a flasher. More like a large relay. It has a SAE number on it. Location number in fuse box is R1 Componet is designated N10
Good Luck
PS a defective hazard switch can also cause the turnsignals not to work

Try turning the red hazard switch in the center console on, then off again. If this switch is halfway between on and off, the turn signals won't work.
