Not clear what you are saying but sounds like you mean that turn signals work as they should jumping circuits at the switch connector? but no hazards with the switch unplugged?

If so that would be a normal test result.
Hazards use another power source and a shift of the hazard light switch built into the multi function switch to do it.

Looking at the diagram I posted, note the hazards get power originating from fuse 13 via the red-wht wire through the hazard flasher then to the switch.
Feeding the Lt green- wht, Lt grn-org, org-lt blu and wht-lt blu circuits making all four lights flash. (pushing the brake pedal feeds the switch through a via a third circuit from the brake light switch. The Lt-grn wire over riding the flasher units effect and stopping the hazard lights from flashing, they remain solid "on" until let off the brake pedal again.

So if your signals all work as they should testing each circuit individually? then the switch is highly suspect as the root cause of your problems. But at this point its not clear to me what you are saying far as that goes.

okay so after jumping the first electrical connection orange w lt blue and brn there was a light blue flash from the instrument cluster and nothing seems to work now i assume a fuse on the back panel blew [/QUOTE]

"brn" is power to taillights circuit and should not be involved in your testing of the turn single circuits.

okay so I think Im confused on the diagram are you able to walk me through the schematic as i dont want to damage anything. When looking at the diagram I thought brn was main power sorry my bad, but is it safe to assum that lt green / white is combination one , lt green / orange is combination 2

First unplug the switch from the harness. Remove both plugs from the switch, the longer plug will be the one you will be working with. Easier if you have a short section of wire with an alligator clip in each end, or a helper to look while you jump with a piece of wire bare at each end.

Turn the key to the run position.

The longer plug, has a light blue wire that is going to be your power wire to test for turn signal function at each corner of the truck.

Start with the corner most in question, front right side (Passenger side)

Jumper a suitable section of wire from the light blue wire over to the white with light blue stripe wire, doing so so as you make solid connection between the two. Front right turn signal and indicator on the dash should flash as long as you have the jumper in place.

Then from that same light blue wire jump it to the light green wire with the white stripe, front left turn signal and indicator on the dash should flash on and off.

Try that a minute and then let me know the result.

Make sure you do remove the switch from the connectors though to be sure it has no impact on your testing of the circuits.

Did you turn the key to the "run" position for the test?

Make sure you don't have any blown fuses.

Yes I have checked all the fuses except for the metal body ones , I could do a continuity test on them to verify , andyes the key was in the on position
There was also a typo in my last message the light blue wire jumped with the Lt green wire had the indicator light illuminated except it was solid and not flashing , however no exterior lights were on

Ok try a rear turn signal.

Light blue wire to light green wire with orange stripe, should be left rear flashing.

Only one bulb load on the flasher unit, so it will flash slower than normally would. Make sure you leave the jumper in place long enough to heat the flasher to cause it to function.

Not really clear there what you mean, when you say "plugged it back in", plugged what back in, the relay? or the multi function switch?
