The 2g door vents are one of my favorite features of the DSM interiors. I don't believe I have ever seen another car with them and if there is they are few and far between. One issue I have had with the past three 2g's I've owned is the somewhat weak nature of the vents after years of use. Which always bothered me because we only have one other set of vents. I get a lot of grief from my tuner friends due to the fact I love my A/C with a passion and refuse to give it up, so I wanted to to something about it.
This weak air pressure is due to the regular use of the air blend door that controls our defrost, panel, and floor vents. This is literally a door that reroutes air through different ducts.
The problem lies in the actuating of this door with the metal cable running from our HVAC controls to the door. The cable begins to stretch over years of use, and because of this the air blend door tends to not close fully, giving us low air pressure in our door vents. ):
Well here's how to fix that, and it's actually quite easy. This took me under an hour and that was with all the trial and error and jacking around to get things figured out.
Begin by removing the lower panel beneath the steering wheel. This is just four 10mm bolts.
Go ahead and take the four phillips head screws out of your HVAC controls. Diamond Star decided to make it a real pain in the ass to take this out, you'll notice it wont come out the front.
Next you will need to remove the stereo unfortunately, I tried this every which way but you can't do it without it. Mounting kit and all.
Next, with the stereo/mounting kit removed, look under and up inside the console at the back of your HVAC controls, you will see on the driver's side a white plastic bracket that is keeping us from sliding those controls out nicely.
There are plastic pins holding this to the metal bracket, what I did here was get a large screwdriver and go to town on it. I did break a pin but afterwards there was zero play in my HVAC unit, it seems to be more designed to help in assembly than anything, so don't fret if you break one.
Now that its loose we are going to muscle the HVAC controls into a funny angle so that we can get a look at the back of the driver's side of the controls.
There's just no good way to do this so just be patient. Once it's at an angle, switch the control all the way over to defrost position, you will notice a cable moving on the back of the HVAC controls. Take a screwdriver and push the loop off.
Now that it's loose you will see two black metal bands holding the cable down, get a straight screwdriver and push it up from below. These can be a real pain but just be patient, you're almost done.
This black clip clamps your air blend door cable into place and controls the slack it has. Get this clip loose from the cable and slide it about 1/4" forwards to reduce the slack in the cable.
The attached image is the clip after I adjusted it.
Next, make sure the cable is secure on the clip and reinstall it. Make sure you adjusted the cable properly and reassemble everything.
Now you can enjoy your door vents to their full potential! Good luck!
I would also like to add that this made a significant difference in my case, but it all depends on the stretch your cable has in it.
