Hi
Here is the problem
Decklid is not opening no power
Door locks not working .
Lights under dash working.
Overhead ones not working.
When i push the door jamb switch , the under dash lights become dim and the overhead ones are lighting, and they stay lighted when i close the doors .
And every attempt to put a 25 amp fuse in the ctsy location the fuse blow instantly ( 10 fuses so far )
Thing funny is, in my owner manual they say 20Amp and on the fuse box 25Amp ??
Have to take out the Batt fuse to get the light to close .
Any idea ?????
That is on a 88GT
It happened to me once but i can't remember what i did to fix it

Check you don't have a penny down inside the lighter socket. Sounds funny but happened to one person here. Otherwise you have to trace down that short. I hate electrical troubleshooting myself. Good luck.

No penny
Thanks

bump
anybody ???
Like we say at Pratt&Whitney ( The plane's on the tarmac waiting )

The phantom courtesy light mystery

Do your courtesy ("floor") lights go on when you turn on the radio? Your radio only works when the dome lights are off? The problem is only a blown fuse, but the cause lies in yet another Pontiac engineering flaw. Back in 84, the cars had a common fuse for the Radio, Cigarette lighter and interior lights. For some reason, the interior lights, trunk release and power door locks got a separate fuse later (which in itself is a good idea). But once again, someone made a mistake, probably on a monday morning, or possibly a friday afternoon.

So the courtesy lights were moved to the "BAT" fuse along with the radio and cigarette lighter, but the remaining interior lights remained on the "CTSY/LID" fuse. All these lamps share a common connection to several switches to ground though. So all these lamps go on if you open a door, or turn on the IP dimmer all the way. The problem is, if one of these circuits blows its fuse and none of the lamp switches are on, the other circuit can draw power through the courtesy lamps. So, if the BAT fuse blows (a dime stuck in the cigarette lighter often does the trick), the radio still gets some power through the lamps. If you turn up the radio, the radio draws more current, and the lamps glow brighter. If you open the door, the radio is shorted, and the lamps go to full brightness.

This can be a problem if you are tracing a current drain in one of these circuits (they're both hot at all times), and unless you know it's just a blown fuse, it can be plain annoying. You can separate these circuits by either opening connector C200 (white and orange wires going into it, near the fusebox), but this only helps for troubleshooting. If you want to permanently cure the problem, cut the orange wire going into splice S210 and move it to splice S125.
