Hey there I'm new to this so I'm not quite sure how it works so I'll post and see what happens. Anyway, I have a 2007 ford f150 that is the v6 4.2l and it's 2wd. It's had the problem stated in the title for some time now. I've replaced ball joints, control arms, tie rod ends and I always make sure the tire pressure is correct. So I'm not sure what to do next. I've heard people say buy new tires but I don't see how that could help. Any suggestions? Also I have a problem with my air switch. It only works on full blast (4) and 1,2 and 3 don't work at all. Also the switch that goes from head and feet to defroster doesn't work. Any suggestions for that? Thanks!

I have a 2006 and when bought it a couple months ago, i too realized the fan speed control did not work on setting 3. But all the other settings worked fine. Did a little research turned out to be the fan speed resistor, advance auto had mine for like $20 took 15 minutes to switch out. Hint its behind the glove box, has i think 4 wires going to it, just unscrew it and replace it with the new one. Theres videos on youtube about it as well. As for the other issues sorry cant help there.

Have you had an alignment or the tires balanced?

T-RUCK Mike

Yes I've had them aligned and balanced like 3 times since i replaced the suspension parts last year.

and your other problem is a blend door...this moves your air flow from defrost/floor/vents.. very common problem.. have you checked your sway bar ??

Ill check on the blend door! And i havent thought of the sway bar but ill for sure check that out. I had a shop look at my truck and they said nothing was wrong with the driving so i feel like i have to find the problems on my own...
