there is a fuse in the fuse box that will turn off the fan until you replace the switch. look in your owners manual to find where it is located

What kind of noises you get and when ( when in drive, in neutral etc )? The noises can come from a worn transmission bearing or transmission clutches. The bad is that for either problem the transmission has to be taken down and/or rebuild.

Check for corrosion in the bulb socket or wiring connection points. This could cause a voltage drop, resulting in a dimmer light. If it looks good, then just replace the bulb with a new one. Use dielectric grease only in the bulb socket to prevent corrosion. Do not use regular grease because it will stop electricity from flowing.

It should be in the main fuze box under the hood or in a separate box for relays. Why do you ask? Have you got a startup problem?

The drive cycle is a series of conditions that you drive a vehicle to prepare the emissions systems for an emmisions test. the drive cycle that is most common to GM vehicles is the following; 1. cold start vehicle and allow to warm up to driving temperature, then set a load on the engine, ie. turn on radio and A/C MAX and headlights. 2. reverse vehicle for approx. 15-20 ft. 3. from a stop, drive vehicle at 35mph @ 25% throttle for 15min 4. allow vehicle to slow to a near stop without using hte brake pedal. 5, begin driving vehivle again 45mph @ 50% throttle for 15-20 min. 6. check for emissions status and test. ***OBDII vehicles (95-99) can have up to (2) two emissions monitors at unready status for PA and can sucessfully submit a "pass" status. vehicles that are 1988 (OBDI) are emissions exempt. 067 Pa Code 177 204 Basis for failure
