clean weep holes sliding glass door .... storm water caused some flooding to my mum & dad's room a few times

 eventually I rolled up sleeves to

clean weep holes sliding glass door 

there usually a couple of small holes to drain water out of the sliding door

but in my case, the previous owner had the sliding door installed with only one weeping hole

anyway, I found it, and cleaned the dirt from the tracks

did some tests, it seems working now

But those weep holes may not drain water quickly enough in a severe rain storm
