Electrical problem
1998 Cadillac Deville V8 Front Wheel Drive Automatic 120000 miles

Sometimes when my car for a day or so, I try to use my keyless remote and it wont unlock my car, then I have to manually unlock it. When I get in it, my interior lights are either off, or flickering on and off as if there was a short. Once I turn the ignition to the on positionl, the the interior lights turn on properly, sometimes when I turn the car off immediately it goes back to flickering on and off and other times it works properly. Ive also noticed when this occurs, my trip odometer in my cluster resets, can anybody please tell me whats wrong with my cadillac?

Do you have any codes in the DIM module

I have received the IPC 1552, 1910, 1983, and ACM 1983 currently, and PZM 2473 in history.

Ok im looking at a 97 caddy book and dtc IPC 1552 is loss of keep alive memory, 1910 is generator L termnial open circuit problem, 1983 is source voltage low, PZM 2473 is high beam output fault.

IPC 1552- battery has been disconected
IPC 1910- IPC could be bad or alt or wiring to IPC from alt could be the prob
IPC 1983- IPC could be bad or charging sys problem
ACM 1983- has something to do with low voltage too, but It wasnt able to find it in my 97 book

these thing need to be checked with a tech 2 diagnostic tool

things I would try is checking all the fuses in the trunk, the back panel up on the back seet comes down there is a fuse box behind it, pull out fuses 1 by 1 and check for power and corrosion on them, replace blown fuses as found
Next I would check the inadvertant power relay for corrosion, its under the hood, drivers side, under the black plastic sheild, behind the headlights, relay is on the strut tower, there is only 1, I think, might try replacing it. Its cheap, might also try reaching your hand down to the alt and wiggling wires on it and pushing in and pulling on them.

These are some things to try

I have a 98 Sedan DeVille and just started dealing with this same problem. The L-Terminal Open Circuit refers to the circuit board inside the panel cluster. I myself, just spent about an hour tearing apart the dash to pull the display apart, to see what was wrong with this circuit board - save yourself the time and get a new cluster panel. Replacing it it fairly easy. Just a heads up - there are a lot of hidden bolts involved. Behind airvents, and, if like my DeVille, you see to have a speaker cover on the dash, they're under there, and under the vent strip that your twighlight sentinal is sticking out of. Start with those, and the rest you will be able to find. Good luck with yours. I'm off to continiue searching for a new cluster panel still: -) Stephani
