Heated windshields where optional for a few years. They draw a lot of current so it has a larger alternator. If you have one, you should have a switch to turn it on somewhere. Check your owners manual.

My 92 eldo. has the heated windshield switch right on the center consuleHeated windshields where optional for a few years. They draw a lot of current so it has a larger alternator. If you have one, you should have a switch to turn it on somewhere. Check your owners manual.
right beside the heated seat controls,very obvious.
RANGER, I researched about the alternator,it actually doesn't have a larger amp. alternator, it has an independant built in charger (within alt.) just for the heated windshield, the alternatot with h/w should have a 3 rd. wire coming out of alt.
Interesting. I knew they where different. Thought they had higher AMP output. Built in charger? What's that?

Theres about 10 alts. on rock auto,they are all 140 amp.,some are marked for h/w and some are not.I cant remember exactly the design of the alt.
for h/w, but I do remember there being a separate power supply for h/w built into alt.,hence the third wire coming out of alt.
I havent even really looked for the third wire,I guess I could compare my 97 sts to my 92 eldo. I shouldnt have used the term charger,but I distinctly remember it having a power source just for the h/w. built right into the alt.
