This is so easy! 2006 Mustang Passenger Side Water Leak

We got tons of rain this week and water started pouring in under the passenger side dash of my 2006 Mustang. I freaked! So I check with Ford they say the leaves and dirt clogged the system and they estimate $500 to fix it. No way... so I googled the problem and find out lots of 05s and 06s have the same problem. Someone suggests pulling off the wiper blades and the cowling to clean out the trash.
So I go for it and after spending 2 hours trying to pull the wiper arms off without a wiper blade puller I go buy one for $12.95. They pop right off with the right tool... duh!
So now I get it all off and I see all the water between the cowling area and the firewall. I reach down and find the rubber grommet on the passenger side, pull it out and all the water drains!! Did the same on the other side. I check the two grommets and they are filled with small debris from the road and trees, I washed them and and put them aside for the moment, I checked the air flow filter which was still in good shape.

I put the rubber grommets back and that's when I notice they are sticking out of the firewall housing a couple of inches! All I really had to do was stick my finger or a short stick up the bottom of the grommets and it would have cleared them.

So if you have water coming in the passenger side of your mustang just open the hood, look at the firewall about 14" down from the top and just right of the battery holder and look for the small rubber boot, it has a thin slit in the bottom of it. Just clear it with your finger and the water will rush out. Do the same on the other side and all the water will be gone. Shop vac the carpet and run the car heater for a while to clear up the water. By the way the dealer who wanted the $500 was Maroone Ford in Fort Lauderdale, what a bunch of crooks!
