DIY : Fixing a broken A/C Louver / Vent Hi All,
I have put the guide in PUG but its useful for any car. When I bought this car the louver adjustment broke in 2 A/C control vents. One from the Co driver side and other one from the center A/C control. I tried numerous method before and this is the best and outlast original A/C vent. Even if you buy a new one it will break within 2 years of usage. Why? Its because of one critical design flaw. There is no strengthening on the sides of "C" clips also called as support lugs. The other and main contributing factor is the plastic rod which clips in the "C" clamp. Its not rounded rather its oval due to the poor molding process. This causes the clip to expand beyond its tolerance value and breaks at the base of the clip. Procedure:
1. Open the louver control with the help of screw driver it will pop out.
2. It fixed in three parts. Gently remove the flow control knob by opening the lugs with the help of the screw driver. You must be very careful it will break easily. Even if you break dont worry it can be fixed back by silicone sealant.
3. Now you need to open the vane (black grill). It may look press fit but its not. On one side you will see a metal pin with a plastic bush. Take a punch or 2~4mm steel bit, place over the pin and punch it with a hammer slightly. You can even push out without hammer. Once its out of the seating push the both ends of the grill evenly. It will come out.
4. I tried with feviquick and these materials does not stick with feviquick and breaks very easily.
5. Be careful when you fix you can easily reverse the position. Once Mseal is set you cant reverse again. Make a quick dry run before applying resin.
6. Wrap a piece of plastic cover with grease coated on the stems and tie with a piece of string. Refer pic.
7. Take a small portion of M seal. Mix well. Make it cylindrical by rolling between the hands. The thickness can be 3~4 mm not more. If its thick then it will obstruct during assembly.
8. Place it over the stem and press firmly to take the shape. Cut off the excess with a knife and shape it. The Purpose of plastic cover is to protect the stems being bonded from the adhesive.
9. Now take 1:1 ratio of Araldite and make a thin coating over Mseal. Put a dab of araldite on the other clips as shown in the pic "end result".
10. Leave 12 hrs atleast for setting. Place between two books and the control knob should be facing down and should touch the floor.
11. Next day remove the thread and cut the plastic cover near the end of the stem using a knife .Reassemble all the parts and fix it in the car.
Regards,
Vijay
