Changing Rear View Mirror Map Light Bulbs (Upgrade Option)

The OEM rear view mirror did not have any lights in it.
However, this is a very popular option that wasn’t standard on Buick Regals (but should have been), so this one is included since a lot of Turbo Regal owners have upgraded to this mirror version.

These mirrors came out of later model Buick Regals (as well as other GM vehicles).
(a few of the Buick vendors carry a mirror similar to this)

This mirror came with 2 white bulbs.




3 on LH (driver side)
2 on RH (passenger side)


WIRE COLOR & PURPOSE (according to factory wiring diagram):
Power wire = orange
Negative wire = black to ground
3rd wire = orange/white stripe, goes to switched white wire from door jam switches



WIRE COLOR & PURPOSE (according to the one we have installed in a Buick Grand National):

2 incoming wires from headliner to plug: brown / white stripe, and a black wire.
Then from that plug TO mirror: 2 black wires. (terminal A = brown from above, terminal C = black from above)

Incoming black (“A” – headliner brown wire) goes to RH switch.
Other side of RH switch has 1 blue wire & 1 yellow wire.
Yellow wire goes to RH side light.
Blue wire goes from RH switch to LH switch.
The other side of RH side light has 1 green wire, which goes to LH side light.
LH side light has 1 black wire (“B”) that attaches with/to the green wire.
Other side of LH light has 1 yellow wire that runs to LH side switch.
Other side of LH switch has 1 blue wire that runs to RH side switch.

Black wire “A” from above, is the one that goes to RH side switch (from terminal A).
Black wire “B” from above, is the one that goes to LH side light (from terminal C).




You can easily add this mirror on if you don’t have it already.
Many vendors still sell it, or find it on ebay.
The existing wires can be found above your headliner, made for the dome light, simply splice the new wires in (if they are not already there waiting for you already).


THIS is the standard mirror that came in the Buick Regal WH1 example car we’re featuring (non-lighted):




The bottom of the mirror has a seam in it that runs lengthwise.
Separate this section by hand.
The lights will be revealed.
Pull the sockets out, and then you can pull the bulbs out.

Reassemble by hand putting the 2 sections back together.
