Still having problems with my SES light...HELP PLEASE.
I have had this problem with my bonneville since I purchased it in early october. The
SES Light was on but not very bright. When I would try to pull codes It would never go out complety just get a little brighter to display my codes. I was getting a code for the ICM so I changed that. The SES light never went out. So the next time, days later
When I checked for codes There were none. So I cleaned the battery termanals and now the SES light is on so bright I can't even check for codes I won't even blink!HELP!!!!!!!!! What should I do next?

Are you SURE you're jumping the correct terminals on the ALDL connector?
Have you tried a genuine scantool?
If the answer is yes to both of these, and you still can't communicate with the PCM, try a PCM from a wrecker.

Yes, I'm sure I'm jumping the correct wires 
Yes, it would before I cleaned the battery conections, but I have not had it scaned since. :( How much should I expect to pay for a pcm? How hard is it to change the prom chip? :(
Thanks again for all your help!

the prom chip is super easy, there are two screws holding a metal cover on the pcm, make sure u wear gloves though cause the static from your hands can be harmful to the prom and the computer, once the cover is removed, the prom should be a blue chip that can be removed by pulling the tabs on each end and pulling up, then put it in the new pcm and reinstall, making sure to wear the gloves at all times
Our 94 has gone through 4 since i have owned it, a mechanic screwed up some wiring in the car, since then it has kinda been a electrical gremlin, but it has been pretty good lately, except the fact that it is in the shop right now:(

It'* harder to change the PCM than the PROM. Can be kinda a PITA to get it out of there. The prom is under a coverplate with only 2 screws. Get a PCM from the wrecker from any of the following:
