Are you getting power to the bulb sockets? Make sure you check your neutral safety switch that is located on the side of the transmission.

No the shifter on the steering column moves the safety neutral switch on the trans. That's where the electrical parts for reverse are located not the steering column

Well my heater works for a little bit and then all of a sudden it starts to trip out and trys to turn on the fan, defroster, ac and heater and different vents at the same time and only way to make it stop is to pull the fuse. It was working fine until the compressor went out and I just by passed it.

Ok check the light green wire coming from the safety neutral switch on the trans. With the test light It should be located on the f slot here is a picture of it to give you a better idea.
