Where is the fuel relay switch on a 2003 Pontiac Grand Am
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?
When you crank, you should, or a helper, be able to hear the pump running under the gas tank. A high pitch whirring / buzzing. If you locate the relay you should be able to feel it click when someone cranks up. It may be fuzed separately so check that.

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.

Noise from tranny
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.
Headlight wiring diagram
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.
The a/c never goes off
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
