Hello all. I just joined the forum. I found this site after looking for solutions to mechancial issues I have been and are having with my 2003 TB I6 LT EXT. You know, the check engine light that never shuts off, the total burn out of all of your exterior lights, and my new one which is the A/C practically shut down my engine at idle when I press the button. This started after battery replacement last week. Any suggestions on the A/C issue will be greatly appreciated.
