The air conditioning drain is on the passenger's side of the firewall. If you do not have air pressure to blow into it to get it to drain then you might use something soft and flexible so as not to put a hole in the evaporator.
this is so bcoz even if cabonate conditioning forms soft scale , but it is a SCALE phosphate conditioning forms soft sludge , which can be removed by blow down operation . so its better than carbonate condiitoning
Fuel level, heat or air conditioning up, both high and low, high only, floor only. Center vents are for air conditioning output only, no heat. Heat is designed to blow out side and floor vents only. NOT center. Center is only for air conditioning or summer vents.
An older kid should be able t blow a bigger balloon because a younger kid would have less breath and would therefore blow the balloon up slower and the older kid would be able to blow the bigger one. Also, the more air in the balloon the harder it will be to blow it up.
