When using the right directional there is a rapid flash on the front, and none at the rear. However, if the directional is left on and the car is turned off and the key removed, the right front light stays on, no flashing. Initially I thought is was a bad rear bulb but I checked it and it is good. Where do I start??

I believe all years have a separate fuse for each signal, so perhaps best to start there. 928 Specialists has fuse/relay layouts at their site, if you don't have a manual: http://928gt.com/

Thanks for the feedback, I checked the fuses and all are good. With my limited electrical knowledge, since it is a constant light when ignition is off, I assume it must bypass the flasher, or would the flasher only work with the ignition on and thus give a constant light?

You could check Greg's site for tips too:

When you inspected the bulb itself to confirm that it was still good, did you check for voltage on the bulb's electrical socket? Since you said that all of the fuses check out fine I presume that either corrosion inside the socket's connections or a short is your culprit.

Went back and checked for corrosion etc. then I went on and put an ohm meter on the bulb terminals to discover that the flashing, while the blinker is on, is reflected however the volt meter reads zero. Could the power going through the relay be interupted there?

It certainly isn't a power supply issue at the central electric board because if that were so, then neither signal would work. Since you found no voltage on the plug terminals, the most likely scenario is either a fault with one of the wires itself or a short. Your switch is obviously doing its job correctly since the front marker is working.

A high ohm value would further support my suspicion of a short. What was your reading?

Check fuse #33 again...

I had forgotten that each individual signal is fuse protected. Are you certain that its good?

I want to thank all for the input, it all came down to poor conection at the fuse. Working great now. Now on to the wipers.
