ted tcb Posted March 22, 2007 Report Share Posted March 22, 2007 Anyone else do this with their new car? My twilight sentinal appeared to be ineffective. My headlights were on constantly, dark or sunny out. When I turned my auto switch off, the DIC suggested "headlights needed". With expensive Xenons, I drove with the twilight sentinal off, and ignored the DIC warning on startup. I cleaned my photocell, but it made no difference. Solution ... my rainsense wipers were in the "on" position, which automatically turns on the headlights, even during bright sunshine. Geez, I felt stupid. Parking the wipers, the auto headlights work perfectly. Anyone else make the same mistake? 1989 FWD Fleetwood, Silver 1995 STS Crimson Pearl on Black leather 1997 STS Diamond White 1999 STS Crimson Pearl 2001 STS Silver 2003 STS, Crimson Pearl Link to comment Share on other sites More sharing options...
95SevilleSLS Posted March 22, 2007 Report Share Posted March 22, 2007 I thought you turned the rainsense wipers on by putting it to the first notch on the delay? I'm pretty sure mine is exactly like yours because mine is a canadian model. Also, if I have my foglights on, my lights will always stay on. As soon as I shut my foglights off, the lights shut off. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...

Must be different interface with the wipers and lights. If it starts raining and the wipers come on .... THEN the headlights come on. Also as 02 WhiteSTS said, if I manually turn on the foglights, the headlights also come on. Just realized you said you PARKED the wipers. Do they not park automatically ? In my opinion they should. I'm sure I will get corrected if I am wrong. Maybe THAT is where your problem lies. Looks to me like you should be able to keep the Rainsense wipers ON all the time. Thats why they ARE Rainsense Wipers. They work automatically when it starts to rain. Link to comment Share on other sites More sharing options...

They work automatically when it starts to rain. I don't have Rainsense Wipers, but that is the sort of behavior I would expect. My Owner's Manual does not specifically address headlamp operation when Rainsense is active. It strongly cautions, however, that the wipers MUST be off if you want to avoid damage at the car wash.

ted tcb Posted March 22, 2007 Author Report Share Posted March 22, 2007 If I put the wiper control arm in the down (lowest) point, the rainsense is not activated, and the auto lights work perfectly. If I put the wiper control arm up 1 position, I'm in the rainsense zone. The headlights turn on immediately, even if the wiper blade hasn't moved. Maybe it has something to do with the Xenon ballasts and bulbs being replaced in 2004 by the dealer? Basically, if the wiper control arm is down (off), when the car is put in gear, the DRL's turn on, and the headlights are off during daylight. If I put the wiper control up 1 position, the light sentinal is overidden, DRL's go off, and the Xenon's pop on. Weird, but no big deal. When I sense rain, I put the rainsense on notice. All other times, I let the twilight sentinal control the lights. Certainly something I can live with ... previous warranty work may have affected the headlight/rainsense interaction. 1989 FWD Fleetwood, Silver 1995 STS Crimson Pearl on Black leather 1997 STS Diamond White 1999 STS Crimson Pearl 2001 STS Silver 2003 STS, Crimson Pearl Link to comment Share on other sites More sharing options...

KevinW Posted March 22, 2007 Report Share Posted March 22, 2007 I believe the "Wiper Activated Headlamps" feature was introduced in 1996 on the FWD models. Some locales require headlamp usage while wipers are in use; it is good practice to activate the exterior lighting under conditions of impaired visibility. ___________________________________________________ Link to comment Share on other sites More sharing options...

This post refers to an 01 DTS which works identical to my setup. http://www.cadillacforums.com/forums/elect...atic+headlights They must have changed the computer interface for the lights and wiper sometime between '01 and '06. My lights only come on when the wipers actually start working. As long as they are not moving (ie not raining) the daytime running lights are on. As soon as it starts raining, the wipers start up, the daytime running lights go off and the headlights come on. When it stops raining and the wipers stop, after 5 or 10 minutes (not sure EXACTLY, probably dependent on ambient light) the headlights turn themselves off and the daytime running lights turn back on. It all happens automagically. You have done nothing except drive. The car does it all by itself. As Warren said, be sure to turn it OFF when going thru a carwash. When mine IS actually OFF, whenever you start the car, the DIC displays RAINSENSE WIPERS OFF. Link to comment Share on other sites More sharing options...
JimD Posted March 22, 2007 Report Share Posted March 22, 2007 I would expect the differences noted relate to '98 through '04 style Sevilles with OEM HID low beams. With HID lamps, you and GM would not want Rainsense to be toggling between low beams and DRL when driving in and out of a light rain. So, GM turns low beams ON whenever the wiper stalk is not in OFF or MIST. And I applaud lawmakers in Georgia and other places that require headlamps ON when the wipers are operating.

95SevilleSLS Posted March 22, 2007 Report Share Posted March 22, 2007 texas Jim Mine works just like yours except for the last part where it tells you that rainsense is off. Jimd I have the OEM HID and mine does nothing like that. If I put my wipers to off I have DRL, I have it in the rainsense positions, I have DRL, no headlights. If the wipers start, then I have headlights. I'm thinking that either they changed the way the rainsense worked for 2002 from 2001 or ted tcb has a very strange problem. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...

I should have said.... when rainsense turns the headlights ON. Which begs a question. With OEM HID lamps, when rainsense turns the headlights ON, do they remain ON after rainsense stops the wipers?

95SevilleSLS Posted March 29, 2007 Report Share Posted March 29, 2007 I was mistaken. When my wipers are in the rainsense or delay position my HID's come on. When I shut off the wipers, the lights shut off. Just found it out today after it rained and my lights were still on. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
tjtjwdad Posted March 30, 2007 Report Share Posted March 30, 2007 Just yesterday I thought I had a problem with mine (01 STS). 1. Headlight switch OFF, headlight twilight sentential OFF and wipers in sense mode (car in gear): DRL's are on and a "HEADLIGHTS SUGGESTED message on the DIC. 2. Headlight switch off, headlight twilight sentential ON and wipers in sense mode (car in gear): Low beams (HIDS) come on and stay on, irregardless if its raining or not. WRT fog lamps, they have no interaction with the DRL or low beams whatso ever. They do go out when the high beams are on. There are "always" lights on on the front of my car. Either DRL's, low beams or high beams. YMMV and hope this helps! Jim Link to comment Share on other sites More sharing options...
95SevilleSLS Posted March 30, 2007 Report Share Posted March 30, 2007 I guess we are just supposed to put the rainsense on when it's raining! -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
Texas Jim Posted March 31, 2007 Report Share Posted March 31, 2007 Assuming daytime .... With Twilight Sentinal "ON" and Rain Sense "ON" if it is not raining, my DRL will be on. If it starts raining, the wipers start automatically, the lowbeam HID's come on and the wipers adjust their speed from intermittent to as fast as they can go, depending on how hard it is rqaining. When it STOPS raining the wipers stop. After a few minutes, assuming the outside light is bright enough, the HID's turn themselves OFF and the DRL's come back on. All of this happens with zero interaction from the driver. The car does it all automatically. I love Cadillacs. They let me be lazy. Link to comment Share on other sites More sharing options...
95SevilleSLS Posted March 31, 2007 Report Share Posted March 31, 2007 Apparently the older ones don't do that. Mine works the same way except for the HID's will stay on as soon as you put the lever to "rainsense." The only way to get drl's is to put the wipers back to "off." Oh well, I'll just have to put the lever down after it rains. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...

It just looks like they took it a step further on models beyond the 2001 model year. Actually, I rarely ever use my wipers as I have a water repell coating on the windshield and it's real nice not having those wipers going.
