This is something new that happened tonight. My Aurora had always had the headlamps flashing-when-cold problem due to the AIR pump tuning on/off for emissions. However, tonight it was doing the same thing, yet far too frequently. previously the lights would dim maybe twice during an entire 25 minute trip. Tonight however, they were dimming once every 20 seconds or so. Everytime this would happen the voltage would drop to 11.7 volts. When coming to a complete stop at idle the voltage was reading between 11 and 12 volts. While crusing however, it reads around 14.8. Ideas?

Check your battery connections, they may be corroded or loose. Also, check your alternator connections. I'd look for bad contacts or grounds somewhere. Good luck.

Have you installed any aftermarket audio equipment? I'd first check there. Is your serpentine belt in good shape? No slipping of the belt?

As I've been researching Intrigues, the frequent flickering seems to be a large problem on the LX5 engine (not such a problem with the L47 Aurora and a nonissue with the 3800). Should anyone ever become interested enough to delve into NHTSA's consumer complaint library via MyCarStats.com (as I do regularly), you'll find nearly no information on the Aurora and a good bit on the Intrigue. Some people reported having these problems early on while the car was still under warranty, and having the dealer chase the problem around unsuccessfully even after replacing light units, alternators, batteries, ABS sensors, dashboards (!), and other large problems. It seems, unfortunately, to be a problem related to underdevelopment that GM "never quite got around" to fixing before killing off the engine (and the brand). The LX5 simply isn't a popular engine (in production numbers) and, having been on the market for a whopping 4 model years, wasn't exactly kink-free even by the end of the run. I've been looking at '99 Intrigues, from the first year that engine was ever in production, and they've got some fairly major problems with this. As an early-build 2001 (I'm thinking yours was early), I'm sure you just got one of the earlier engines.

I have had this problem since I bought the car new. After researching the problem from the dealer, Olds has a bulletin out on this problem. The dealer at the time told me that there is an alternator upgrade but this did not do much to resolve the symptoms.
As I recall, the Dealer and a TSB mentioned this is related to the air Pump. I would check with a local GM dealer to lookup the TSB for this issue. And resolve accordingly.
There are on-line services where you can purchase the Technical Service Bulletins on-line bulletins.
