2003 Pontiac Bonneville Q&A
2003 Pontiac Bonneville Question: AC water drains to the int. passenger floor repeatedly & shorts electrical?
Has a professional mechanic ever checked it out? - pushrod
Had the same problem, fixed now. The process is documented on my thread here: http://www.pontiacbonnevilleclub.com/forum/2000-2005-other-than-gxp/topic38953.html It turns out GM designed an AC drain tube that goes right through the firewall and into the interior passenger floor. Someone might know why. You can see photos halfway down the page here - http://www.pontiacbonnevilleclub.com/forum/2000-2005-other-than-gxp/topic38953.html Meineke got at my tube from under the car on a lift, cheap fix. - 03-SteelBlue-SLE
