Electronic Stability Control Related Problems of the 2007 Ford Focus

Electronic Stability Control problem

I have a 2007 Ford Focus zx5 and have had nothing but problems with the climate control switches and cables I have replaced these several time from the control lever cable,heat control cable they have both broke several times and they will work for a while and then they break or will not work, I recently purchased the whole control switch with heat, climate control, and speed and the cables and the mechanism that it hooks up to and within a week it does not work again, when I go from vent to defrost it will not go to defrost it is on the vents with this being said this is very dangerous especially if your f=driving in bad weather it could cause and accident. I have looked up these issues and all of the older Focuses have this same issue there are tons of videos and forms from other people with this complaint and if you call Ford they advise there is nothing they can do. That is why there are so many accidents because of the manufactures make cars cheap and sell them and do not care about peoples safety. What happens on these cars that the flap door in the dash in front of the heater core is so close that it melts the door so that the flap does not work properly what this should had been made out of is a aviation type aluminum and the housing around it so it does not melt and possibly cause a fire in the dash.
