do anyone know why a 2003 pontiac grand Am wont start when its cold outside? this same questions was asked before in 2009!!
odds on your auto choke is knackered and not working properly that or one of the sensors is knackered for cold starts
Check fuse 37 in underhood fuse box should say for A/C. If this is blown car won't start when cold outside. If it is blown there is a problem with the A/C clutch circuit or A/C clutch. Unplug A/C clutch replace fuse see if car starts.
I have a 2004 Grand Am, and after reading this because my car was also not starting only in the cold. I found that fuse #37 was blown as well, changed it out and car starts right up. Now though if it drops below 40 to 35 degrees outside the car will start but will blow that same fuse. have had to change it 5 times in two months.
