hi! pa-advise naman po on the following:

1. where can i have the aircon vents tightened or replaced (if needed)? ayoko naman kasing siksikan ng pieces of paper eh.
2. hazard light button works but doesn't hold down when no longer pressed. due for replacement na kaya 'to?
3. tire pressure that's best for fuel efficience and longer tread life?
4. my el has an 8km/L fuel consumption. is it right to say na malakas 'to? any suggestions on how this can be improved? i'd really appreciate it.

tnx in advance!
