    Mine is doing the same thing it will be fine then all the sudden the high beams keep blinking like a lose wire but you can hear a click from an automatic switch as it blinks. this all started after converting the sealed beam to hollow headlights. I think it's the headlights drawing to much power through the switch intern cause's it to overheat. I will let you know if I find the problem

With lots of the early 90's vehicles headlight malfunction can be caused by a disfunctional alternator either you may need to replace the alternator or sometime what can happen is the belt may be to loose if its not either of these you may just need a new battery

My 99 Dodge Durango 2 wheel drive randomly shuts off and sometimes wont start until it cools down for 20 minuteswhat is the problem I have replaced the computer and it keeps doing the same thing

Could be the idle control valve or stepper motor as it's sometimes called.if clogged or sticking it will cause engine to stall. Unplug it unbolt it give it a good squirt of carburettor cleaner inside this will dissolve the carbon and tarnish inside.let it dry for about 30 mins replace back on engine plug it back in an see if that cures it.

What is the drive cycle of a 2003 grand am

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.
