2000 Oldsmobile Intrigue

I just purchased my 2000 Intrigue and there are a few issues. One that started yesterday is as follows. The signal lights and hazard lights don't always work. They will simply stop functioning entirely and the come back. The second issue that I believe is related is the instrument panel, heater fan and headlights. At idle as well as when the car is running the will all seem to lose power and regain it. The fan will blow slower the lights will dim and the instrument panel will dim also. The engine seems unaffected.

Any thoughts as to where I can look?
Do you
have the same problem?

Since the turn signals and hazard lamps are affected, and the both run through the hazard switch, that is what I would lean toward on that issue. When the turn signals are inoperative, push the hazard switch around and see if it changes.

On the low power issue, take a look at this bulletin and see what you think, It almost describes your concern verbatim.

#01-06-03-001A: Headlamps/Interior Lights Dim Intermittently in Cold Weather (Replace Generator) - (Apr 11, 2002)

Subject: Headlamps/Interior Lights Dim Intermittently in Cold Weather (Replace Generator)

Models: 1999-2002 Oldsmobile Intrigue with 3.5L V6 Engine (VIN H - RPO LX5)

This bulletin is being revised to add VIN breakpoints and to include information on 2001-2002 vehicles which may exhibit a similar condition. Please discard Corporate Bulletin Number 01-06-03-001 (Section 06 - Engine).

Important: Short term voltage drops (flickers/fluctuations of lights) may occur whenever high demands are placed on the vehicle's electrical system. This is considered a normal generator output characteristic and a repair may not be necessary.

Some owners of the 1999-2001 model year Oldsmobile Intrigue built prior to VIN breakpoint 1F237068 may comment on an intermittent condition where the headlamps or interior lights may dim intermittently. This condition may also be noted in the blower speed slowing or changing pitch intermittently. Some 2001-2002 model year vehicles built after the VIN breakpoint may exhibit a similar condition.

On 1999-2001 vehicles built before the VIN breakpoint, this condition may be caused by intermittent low voltage. Transient engine vibrations may induce the generator to experience field discontinuity. This state results in a voltage spike that causes the voltage regulator to reset. During this period, the electrical system drops to battery voltage.

On 2001-2002 vehicles built after the VIN breakpoint, the voltage drop may be due to the electric AIR (Air Injector Reactor) pump cycling. This electric pump causes a large current draw when it starts.

Important: At no time during the above conditions will the headlamps go out.

On 1999-2001 vehicles built before the VIN breakpoint, replace the generator with a revised generator, P/N 10464469, that has circuitry to inhibit the voltage regulator reset condition. Use the procedure below to replace the generator.
