#79 of 209 Electrical issues - antenna, locks, interior lights
Jan 31, 2007 (5:43 am)
1993 Buick LeSabre Custom - 220k miles
It's my wife's daily driver car, and the power antenna quit working about six months ago. The motor ran all the time, so we just disconnected the relay. Not a problem, we just left it up, put it down when washing the car manually, etc. Three weeks ago, the antenna snapped during an ice storm, so I had to do something.
This weekend, I replaced the power antenna with a new motor and antenna (through an aftermarket kit from Antennax.com). I followed the directions exactly, splicing the wires into the old wires leading from the old motor into the harness. There were three wires - a green, a black and a white. The green is powered when the radio is on, the white is powered all the time, and the black was a ground wire. Both the old antenna and the new one had a separate grounding - a wire leading to a bolt attached to the frame.
During the repair job, the antenna went up and down with the radio being turned on and off, then stopped working entirely. The interior lights (dome, door lights, entry lights, etc.) quit working, as did the power door locks.
I have checked all the fuses in the driver's footwell panel and have found none to be out. What is the problem here?
1) Is there another fuse I need to check (in the passenger-side panel, behind the sound deadener OR under the hood)?
2) Is the power relay (black box) where the antenna plugs in to the power supply bad? How can I tell if it is?
3) What should I do next?
Thanks for your help in advance. I have enjoyed reading other responses on this board and hope someone can help me figure this out.

There should be a fuse for the radio power that is under the dash -- don't recall where.
There also is another circuit that powers the radio and keeps power to one portion which keeps the memory alive for station settings.
The dome lights will be fused also and that may be the circuit that supplies radio with constant power for memory.
I don't know how the circuits are wired for the power antenna. I knew long ago when I had a Cutlass with one.
The antenna itself may not be grounded? See if it works giving it power on the proper wires or use resistant checking to be sure it didn't burn out...
My 93 leSAbre had a power antenna too and it broke the cable inside. I just left it up. If I did a replacement I would have just put in a regular antenna. Power ain't worth the trouble.
Let us know what you find checking the power antenna itself.
I hate to suggest but there's a ground buss next to driver's door in A-pillar area going under the door sill that's wrapped up in lots of tape... but when those get corroded from constant moisture there usually are other symptoms; door looks don't work, AC loses control of system and works in default... Any other symptoms?

There was a 15-amp fuse which controlled the power antenna, the interior lights and the power door locks. That fuse was blown. I replaced and all perform again.
The problem now is that the "always-on" 12 volt power at the power antenna is now un-powered. The "momentary" power when the radio is on has 12 volts all the time.
The grounding is adequate. I am concerned it could be the relay. Replaced the relay, and that did not solve the problem.
I'm really confused. antenna is stuck in the "down" state.
The constant power wire is orange, momentary power is pink/red, and the ground wire is black.
Thanks for your help thus far.

Has anyone ever had to replace a dimmer switch on a 2003 LaSabre. Is it difficult and what will it cost?

I'm not sure if there's another route and fuse for the power to the always on wire. I don't know what year it is.
But with the trrouble levels with power antennas, I'd connect power to the on and run the antenna up once and leave it up. Run a fused power cable from the battery directly if you're sure which wire is hot all the time.
I'd disconnect the connector in the trunk and be done with it. They eventually break... That's my personal opinion.
I used to know how the motor and switching was wired. It was funny. sort of like windshield wiper motors.

You're right about me being tired of it. I've been fighting it for a month, and this is still not working.
The fuse continues to blow - it's a 15 amp that runs into that same section. It runs interior lights, power locks and the power antenna. The fuses have been seriously blown - not just the little burn but "no fuse metal left" blown. I am considering your idea of running it up and leaving it up.
This may be wrong, but the only way I was able to get the antenna to fire - I figured this out when working on it again this weekend - was to cross the wires to get the antenna up. it would activate when all (12-volt constant and the 12-volt powered-when-radio-is-on) the wires were crossed, and then it would retract when the wires were uncrossed. I'm sure this is a condition that could blow a fuse.
Thanks for your help on this. The friendly local dealer says $200 to diagnose and fix this problem - I'm not sure radio reception on a $1500 car is worth that.
I will be back in touch once something else happens on this car. It just needs to last us another year - the car has 230k now.
#86 of 209 03 La Sabre Dimmer Switch

I'm still in the dark as to how to replace a headlight dimmer switch on a 2003 La Sabre. Can anyone throw some light on this topic including estimated cost?

Try looking up the switch on rockauto.com
and gmpartsdirect.com. I believe I found the switch for a few hundred dollars. It used to be that the lever screwed or snapped into the linkage at the top of the columna dn the switch was down on the bottom of the column.
What I found was a group of wires and parts that look like a lot of stuff is all a part of the unit.
This is a part number from their listing
It's a Delco number.
go to Buick, LeSabre limited, electrical switch and relay, dmmer switch

Thank you for your assistance, I'll try to remove the lever and see if I can get at the switch.
