I just replaced my bulbs in the dash with LED's. I tested it out before i put it back together. when I use the turn signal to go right all the lights blink. when i have the head lights on and turn left the lights freeze instead of blink. any ideas? thank you.

Shouldn't have any issues at all. I did this on mine without any issues.

Did you replace anything else with LEDs other than the dashboard lights?
 
Yes, I replaced my front headlights with Halo LED's a few weeks ago. I did replace the relay in the steering column to make them work at normal speeds. i am also in the process of replacing my rear to LED. I currently have the left rear light disconnected? Would that do anything? Here is the bulb i used.
Thanks for the help.

Pull the instrument cluster back out and remove and inspect connectors ! Be careful !! Then you need to make sure all bulbs are correctly seated, I assume in your last post you pulled out leds and replaced with original bulbs?? What's up with rear lights are they disconnected or did they go out after this work you've done ??
Try the lights when you pull the connectors out of cluster ! Try all lights with cluster disconnected, if they work then you have a connector problem or circuit board problem. Improper bulbs or improperly seating of bulbs in cluster could cause a lot of those problems.
 
i took off the instrument cluster to test. the rear lights still don't work. when i do the turn signals only the center rear break light blinks.
nothing else works in the rear. no break, no reverse, no rear lights.
So i replaced the multiswitch. that might have been part of the issue but things are still not working. the front lights now work great. the directionals work in the front. the rear is still messed up weird. none of the lights work except the middle rear break light. the middle break light comes on when i turn on the car lights. but i get nothing from the rear lights. has anyone seen this before?
 
I found out what the problem was. I was in the process of changing out my rear lights during all this. they were just hanging there. No ground.
Thanks for all the help getting it back to here though.
