You might ahve to cut the plastic covering to inspect in between.   Check the other ends of the cables where they ground for good, fresh contact.   Your battery might have a broken post.   YOu might turn the HVAC to off with the key ON if you're getting any power, especially if you have the automatic dual AC.\, before disconnecting the battery to do all this checking.

Thanks for the reply. I thought that might be the problem so I checked the voltage between the battery posts and that looked ok. Thinking it may be a bad ground, I checked the voltage between the positive side of the battery and the frame... that looked ok also. Am I missing something?

Wonder of wonders! I took imidazol97's advice and cleaned my terminals and battery cables. They looked clean as a whistle on the outside but I discovered that they were badly corroded once I took the cables off the battery. A little sandpaper and elbow grease and now everything is as good as new! Thanks! Replies to this message: imidazol97 (Jan 09, 2009 12:55 pm)
