its the vent door. next time try hitting the switch for recycle/fresh air off and on. that may help.
Bad tire? Rotate and see if thumping changes
This is because of rabbits communicating.
On my 2002 the ignition switch was hanging up causing a similar situation. A shot of WD40 into the key hole cleared it up, over a year ago.
The Driver!
It is most likely caused by a rotor that is warped. When you step on the brake pedal, the brake pads pulse against the uneven surface, causing a "thumping" you can feel. Other possibilities could include a bad wheel bearing or a tire that has tread that is separating.
This could be a loose exhaust bracket causing it to hit the underside on acceleration.
An electrical storm can potentially damage your car by causing power surges that can harm the electrical systems, such as the battery, ignition system, and computer. Lightning strikes can also cause direct damage to the vehicle's electrical components or starting a fire if it hits the car directly. It is recommended to park your car in a garage or under a shelter during electrical storms to minimize any risk of damage.
No, my house has not been hit by lightning, causing any electrical problems.
I have a 95 Camaro as well with the same problem. My problem was that my cam was eating up my lifters, and then they tried to fix the problem, and adjusted the valves wrong -- thus causing the thumping noise.AnswerIf you hear it when first pulling out or turning from a stop, it could be loose or damaged motor mounts.
Could be at least two things - Electrical short - Electromagnetic coupling between power wires for ignition and window/roof motor control wires. Turn on power bleeds onto motor contol lines and induces a electrical current onto the wires causing them to run. Just a guess
You may have a electrical short in your ignition switch or in your fuse relay box,check to see if any water may have gotten into the fuse box relays.
Heater core has air in it and or plugging up.
