I just recently took my car to a well known mechanic to get my a/c fixed. The main problem was my regulator valve; it was clogged. They said they had to take my whole dash off to replace this valve. After being in the shop for three days i finally got her back. When i get in and adjust my steering wheel it was uneasy to move up and down. It also wobbled to the left and right when adjusting it but when i lock it in place it stays tightly. Also my ****pit is much louder. I hear the turbo spooling up much much louder and I also hear other engine noises that sound normal but have never been able to hear them before from inside. The noises seem like they are coming from underneath the steering wheel near the pedals. i was thinking they didn't replace the insulation right. Sorry for the long post, please let me know if you have any ideas why I hear all this noise all the sudden.
