03 GL 1800 overheats

Post by bhenderson336 » Fri Sep 09, 2016 2:39 pm

On a recent trip, I was in stop and go traffic for two hours. My Wing 2003 1800 overheated, the two others riding with me had no problem. I found out in 2003 there was a service bulletin and if a person had this problem the dealer would replace the control module (main computer) Now I find out this free replacement stopped in 2006. Not only that but no one is making them anymore. The only solution the dealer gave me was to do all stop and go traffic in 2nd gear (it confuses the computer and makes the fan kick on earlier)...at the cost of ruining the transmission. Has anyone else run into this? What solutions have you found. Brian Greensboro, NC. Chapter W

I see you've been waiting a while... I don't have 'THE' answer but a suggestion.
I've read cars Control Module (CM) can be reprogrammed, maybe find out if your Wing's CM be reprogrammed?
Might have to do a little Net searching in auto sections, particularly hot rods.

I've never heard of keeping it in 2nd is going to trick anything, but maybe put yourself into a false sense of security (doing so won't hurt your tranny, but maybe your clutch). However, keeping it under 15 mph will prevent the fans from shutting down. Once you get over 15, the fans stop and no cooling air through the radiators unless you're doing 30 or so.
