well first, i know next to nothing about cars, so these could be easy fixes and i wouldn't know. one my a/c's not blowing cold anymore. a friend told me to replace the coolant and possibly get it recharged, is this good advice? and second there's a squeaking noise when i go around turns, and every so often when just driving. it's usually at lower speeds (ie <20mph) and sounds like it's coming out of the front passenger side wheel well? Any advice on what to do to fix these would be helpful.
