    Heated windshield

    Got a question. I have a 95 Seville with the heated winshield option and I was wondering how that works? I'm not sure if it is working properly. It appears to me that there must be an electric heater in the defrost duct, however the air coming out does not feel warm at all. Does anyone else have this option and possibly shed some light.

    Re: Heated windshield

    The entire windshield is coated with an electrical resistance film. The alternator has a special set of windings in the field to power the resistance film which heats up sort of like the grid on the rear window. In sunlight the glass looks like it has faint "sunglasses" on - a sort of metallic shiny reflection.

    It's the windshield itself, not the heater/defrost duct. If it doesn't work you're in the connector/wiring/fuse/circuit breaker/alternator () business.

    Look at the legend down in the lower passenger corner of the glass. Is there any indication, from the wording, that the windshield has a coating or something special ? You may have a non-heated replacement windshield.

    I have a 92 eldo. with heated w/s, subs explanation is right on, all I can add is under certain light conditions the top area of windshield (maybe 5 to 6 inches from top) shows up as a coppery/brass mottled tone,much the same pattern as burl walnut,I went outside to look at mine and can not see it now,
    I will ask obvious question, do you have the "de-icer" conrol button on your consul near the heated seat buttons?.

    Re: Heated windshield

    I think someone before me replaced the windshield with the non-heated version, I see no "film" or "coating" of any sort. My heated windshield button is on the same panel as the climate control right above the rear defrost button. The light does come on when I push the button and the defrost blower motor goes to "high" even if I don't have the defrost on. Guess I hope the windshield gets cracked so I can have the insurance replace it with the heated one that is suppose to be in there.

    Thanks for the response guys.

    Re: Heated windshield

    If you still have the RPO (Regular Production Option) sticker under the spare tire cover, enter all the 3-character codes into www.cadillacfaq.com/rpo/index.php to see what's built into your car. It's entirely possible that the heated windshield was not optioned in.

    My 2002 STS also has the heated windshield button/logo, but has no heated windshield and never did. Later today I'll fool around with the HVAC system and see if that button seems to change any airflow or temp settings. I don't remember........There's NO reference to the button in the shop manual or Alldata.

    EDIT: When all else fails, read the directions !! The Owner's manual, HVAC systems, says the button diverts (coolant system temp) heat and most of the airflow to the windshield vents when pressed. It's sort of a HVAC control panel override. I can turn the A/C compressor OFF manually and use the mode settings on the panel to control airflow only. When the windshield (DEFROST) button is pressed most of the air is sent to the windshield vents and the A/C compressor runs to dry that air.

    That would not be surprising. Those windshields are well over $1000 (if you can find one).
