Ok, so I took some grass trimmer spool just to check the drains before I start pulling my interior pieces to check for the kink that was described in the above ^^ post, and on the passenger side I was only able to get the wire down about 6 inches, whereas the drivers side I was able to get the wire down about 2 feet!

Should I try compressed air down the drain first, before pulling panels, or should I just pull them and it would most likely be the drain is kinked?
