Hey, My 2010 Hhr is having leaking water (i think clean) everytime we take a decent left turn, I don’t think it’s the butyl patch or cowl thing, blowing air on the a/c drain helped, but didn’t fix, help?

 

Welcome
2010 doesn't have a butyl patch.
What does "blowing air on the drain helped, but didn’t fix" mean. Are you talking about the AC drain ?

 

Yes, my father said he blew on the ac drain and it all came out, but recently its starting to do it again so i was lookin for a fix

(i’ll edit the post to be more specific)

 

Blowing air in the drain probably just moved the gunk obstructing the drain. The water then drained out. Now weeks, months, years later (you didn't say how long) that gunk has probably moved back and replugged the drain tube.

 

Do you have a sunroof, per chance?
check the wiring boots at the door hinge area , if that is disturbed that’ll allow water into the cabin

 

You can get a aerosol can of AC vent cleaner at the local auto parts store. You spray it into the center vents and foams up in the drain pan killing all of the scum mold.
