Hi I have a Daewoo Lanos Sx from 1999.I have a problem in the vent selector. It seems that the guides for window/front/feet etc vent selector broke. The rest of the system is ok. I have cold and hot air and fan speed is ok also. What I would like to know its from where can I fix the guides. From front panel and taking all the panel or from the hood to get an easier access? Ty in advance.
