So i got this car about 6 months ago and from the start I’ve had problems with the climate control system, driving it home the a/c system was stuck on and the lights all worked but you couldn’t change anything. So my dad unhooked the battery and that reset the system so it worked for about an hour and then it shut off again but this time the whole thing didn’t work like the lights were off and couldn’t change again. So I took it back to the dealership and they said something about the climate control head and that they cleaned it and that helped it work again but it didn’t last long. Since then it goes in and out often. It stays on whatever setting I had it on when it last worked so it’s got a little heat coming through at all times but I can’t change anything or use my defrost. It’s getting very cold and I would just like some help please and thank you!
