A/C Controls Swap
Swapping the A/C controls to the Trans-Am type on a Camaro.
Although this article was based on swapping the A/C controls to the Trans-Am type,
the instructions apply to a regular replacement of the controls, simply by omitting
the last 2 steps. The A/C controls were starting to look pretty shady, but my reason
for changing over to the T/A type is simple: looks. The Camaro controls are very
plain, and hard to see at night. On the other hand, the Trans-Am controls have the
hot/cold controls in blue/red, and light up very well at night since they have 2 more
lights. Anyway here goes:
Tools Needed:
- Flathead screwdriver or needle-nosed pliers
- T-15 torx bit or torx scredriver
- 7mm bit or screwdriver
- 1/4′ bit or screwdriver
- -optional- Something to cut and smooth out plastic (I used wire cutters and a fillet knife).
A dremel type
tool with cutting and sanding attachments would have been better.
Getting to the Controls:
First thing to do is to remove the panel that goes over the A/C controls and stereo.
Use the torx bit or a torx screwdriver to remove it. Once that’s off you can
take the 3 screws (highlighted in blue) that hold the A/C control panel in. They are
of the 7mm type:
You can now slide the control panel out and remove the wiring, vaccum tubing, and
the metal cable.
RED: wiring for the high/low switch.
BLUE: 2nd vacuum tubing connector (not present on all cars).
GREEN: more wiring for the blower motor.
YELLOW: Main vacuum tubing connector.
ORANGE: that puny excuse for a light.
The cable is on the reverse side.
Removing Electrical Connectors:
The electrical connectors are of the regular snap on/push-up-on-plastic-clip(s) off type,
except for the light which twists off.
Removing Vacuum Tubing Connectors:
The smaller vacuum connector simply pulls out. For the main vacuum tubing connector
(highlighted in yellow above), you need
to slide out the little metal clips that hold it in. This is most easily accomplished
with a screwdriver or needle-nosed pliers. I used a screwdriver:
Removing the Cable:
This is done in two steps. First, you need to press on this little tab with
a screwdriver while pulling the cable away from the control panel. The tab is on the top
of the panel next to the 2nd vacuum tubing connector (highlighted in blue above), but the cable is on the bottom.
Here’s the tab, with everything removed for clarity (the little part sticking out of it is
what’s holding the cable in):
Now the only thing holding the cable in is its attachment to the hot/cold slider thing,
which is easily removed. Sorry about the blurry pic:
Transferring the hot/cold slider to vacuum connector piece:
OK this next piece may or may not apply to you. The replacement A/C controls only had one
of the vacuum tubing connectors, my A/C had two. So I had to transfer a piece over. It
connects to the hot/cold slider and to the 2nd vacuum tubing connector (highlighted in
blue above). The screw holding it in is of
the 1/4′ type.
Again, sorry about the blurry pic:
These next steps are only necessary if you’re switching over to the Trans-Am controls.
If you’re swapping like for like, install is reverse of removal.
As mentioned earlier, the Trans-Am A/C controls have 3 lights. They’re hooked up to a
connector that needs to be attached to the gray/black wires that go to the Camaro’s
single light. The wires on the connector are also gray and black, so no problem figuring
out which wire plugs in to which. Well if there is, perhaps you shouldn’t be doing this in
the first place. Anyway, I soldered (butane soldering irons kick ass!) the connector in
and covered the soldering job with shrink tubing, but use any method of hooking up two
wires you want:
Well, that’s pretty much it. Just hook everything back up, slide the new A/C controls in,
screw it in and that’s it. But wait, the panel that goes over the A/C controls will cover
up the top of the controls. This has no effect on functionality, but it looks dumb. So I had
to increase the size of the opening. Just cut until the opening goes all the way to where
the panel starts to slant. A pair of wire cutters was used to remove most of the material,
a fillet knife to smooth it out. Here’s the finished install, much better than before, I must say:
