Pontiac Repair: 1992 Pontiac Bonneville SSE, pontiac bonneville, drain hoses

Question
A lot of water leaking in heavy rain over driver visor but A LOT of water on driver side floor.(I do live on a hill and park facing downhill).  IF it's possibly the sun roof drain hoses what do I clean/clear them with?  A long pipe cleaner?  Didn't want to attempt a coat hanger.  Also water in the trunk.  I own two identical 1992 Pointiac Bonnevilles and both have the same issue.  Was going to get a newer car last year but lost my job, go figure.

Answer
Hi Lisa:

a long pipe cleaner or some spooled safety wire will work, Both of thmem are flexable and will not puncture the tubes. If they are not plugged they may have come off the sunroof assembly that is common as well. You will have to pull down the headliner to verify that for sure. If yout think you have them cleared just pour a small cup of water into the sunroof track and see if it drains out the front and rear of the car. Good luck
