The signal lights use to work until we started hauling things in it...they wont work at all except when you turn the right signal on then both blinks .I don't know what is going on with them.....as for the 4-wheel drive i think it might be warped or the other drive shaft might be bad someone told me it could be warped cause when i drive my blazer it vibrates the whole vechicle.I wished i knew more about things like that........:banghead:

On the drive shaft check u jounts and splines on shaft slip joints.

The turn signals I would drop steering column splash cover and find the turn signal wiring plug.
The check for what is going into and coming out of turn signal switch.
Make sure 4 way switch is not stuck on to.
Also a trailor light plug and add on wiring for it can be bad or shorting across to.

Dark green wire is right turn and stop light and yellow wire is left turn and stop light.
Go for them and see what you have.
