Check the fuse in the fuse box. If that is good then you might want to look into getting a new sunroof motor. The gears in the motor are plastic so one of them may have some broken or missing teeth. If you can hear the motor run then replace the motor. Also, maybe the switch is bad. Check all of the connections and make sure that they are seated right.

I found out the hard way -this is soooo important. It is imperative that you use the orange dexcool. it is designed to withstand certain temperature. If not used properly - it could start a domino effect thats very costly. T.M.I One time i let my boyfriend check my oil- simple enough right? like most people do, the water level was checked as well. he filled reserve w/ plain water all the way to the top ( instead of where coolant level line is) The results were over heating (plus found out later after melted heads) that the threads to reserve cap were stripped. which is what lead to lake of pressure in coolant line.

how do you remove a starter from 2003 3.4 grand am

how do you remove a starter from 2003 3.4 grand am

On the 3.4-liter model, the starter is instead mounted at the lower-rear of the engine against the flywheel. The procedure to remove the starter is as follows:--1) First of all lift the hood on the Grand Am and locate the car's battery. Identify the negative post on the battery by its minus symbol on the top of the battery case. Use a socket wrench to loosen and remove the cable from its post on the battery. 2) Make sure the cable's not contacting any other metal or the engine. 3)  Then Open the driver door and fully engage the Grand Am's emergency brake. Raise the car at its jacking point on the front passenger side using a car jack. The bottom of the tire should visibly measure eight to nine inches from the ground.
4) 
Position a jack stand slightly left of the car jack. Remove the locking pin from the support arm on the jack stand. Raise the support arm to accommodate the height of the car jack. 5)  Return the locking pin to the support arm of the jack stand to secure its height. Slightly lower the car jack so that the jack stand can bear some of the car's weight. Do not remove the car jack. Rock the car back and forward slightly to assure it will remain stable.6)Return the locking pin to the support arm of the jack stand to secure its height. Slightly lower the car jack so that the jack stand can bear some of the car's weight. Do not remove the car jack. Rock the car back and forward slightly to assure it will remain stable.7) Slide under the Grand Am head first and locate the starter. It will resemble a large elongated golden or black capsule. The solenoid will attach directly to it and will resemble a smaller capsule as well.8)Remove the bolts securing the flywheel cover with a socket wrench in your  3.4L Grand Am. Lower the cover from its mounting position on the flywheel. Place the cover and its securing bolt to the side of the work area.9) Remove the starter's retaining bolts at its base where it mounts against the engine. Start with the top bolt. Before you remove the lower starter bolt, support the starter with your free hand. Remove the bolt and place both hands on the starter as you lower it away from its mounting position.
Thanks. you can rate this solution and show your appreciation.

I just replaced the blower motor and resistor in my daughters 02 Grand Am 3.4l. Not sure if it's a total fix but it's a start to the elimination process and only cost $40 for both parts. Will repost if it's not solved. Hope this helps someone in the meantime looking for answers.

Can low steering fluid cause mechanical problems

Problems associated with low power steering fluid…

Hard Vehicle Steering
A low power steering fluid level can often times cause a vehicle's steering to become hard and labored. Adequate amounts of power steering fluid are necessary to enable a vehicle's power steering system to function and operate at optimum levels. A lack of power steering fluid in a vehicle's power steering system reduces the amount of hydraulic fluid pressure necessary to efficiently operating the various parts of the entire power steering system. Power steering fluid supplies the fluid force needed to operate the power steering gears and to enable power steering gearbox operation. Low power steering fluid levels reduce this hydraulic pressure, which commonly results in hard vehicle steering.

Pump Noise
It is very common for a low power steering fluid level to cause significant power steering pump noise. An adequate amount of power steering fluid is required to ensure the proper function and longevity of a power steering pump unit, which is a belt-driven pump responsible for housing and circulating power steering pump fluid. A low level of power steering fluid results in increased power steering pump friction, heat, and wear, all of which can significantly reduce the operational life of the power steering pump while at the same time cause excessive power steering pump noise.

Fluid Boiling
Many times a low power steering fluid level can result in excessive heating of power steering fluid, a condition that can seriously degrade the fluid and cause it to boil. A low power steering fluid level results in less available fluid to both lubricate and cool a power steering pump unit. A lack of power steering pump lubrication and cooling leads to excessive heat being generated within the power steering pump unit itself, a condition that translates into the available level of power steering fluid becoming super-heated and degraded. When this happens it is common for the power steering fluid to boil and lose all of its lubricating and heat-reducing capabilities.

Gearbox Wear
The power steering gearbox is a set of gears within a vehicle's power steering system designed to facilitate movement of a vehicle's front wheels. The power steering gearbox is connected to the power steering pump by hydraulic fluid lines that deliver a constant supply of power steering fluid to the power steering gearbox. A low power steering fluid level, especially a chronic and severe low power steering fluid level, can lead to increased friction and wear within the power steering gearbox assembly, a condition that can significantly shorten the operational life of the power steering gearbox and negatively affect its operation

My 2003 Pontiac Grand AM is overheating. I have

My 2003 Pontiac Grand AM is overheating. I have had the water pump, thermostat, and everything along with it replaced already. From what my husband can tell, the radiator fan is not coming on when it should. We have to drive it with the AC on all the time in order for the fan to stay on and keep the car from overheating. Any help/advise would be greatly appreciated! Thank you!

you need to have your car checked with a hand held computer,with this tool you can do special test like turn the cooling fans on, and with the tool you can see what temperature the computer sees,if your temperature sending unit is lying ,like if your engine is at 215 degrees and over heating, the temperature sending unit might only be telling the computer it's at 190 degrees,which the computer will not turn the fans on.and with a hand held tool you can check the fan relay which turns the fan on.or the fan motor could just need replaced,so if you do special test and turn the fans on with this tool,you can do all your testing with a test light.

Service Engine Soon light - 2003 Pontiac Grand Am

Only problem I've ever had out of this car was replacing front brakes and rotors two years ago. Drives great. Does have 93,000 miles on it and the only service I've given it has been regular oil changes (last one was two days ago). Service Engine Soon light came on while driving to work today. No noises or malfunctions. I've read several posts on the Internet by people who say a loose fuel cap or loose cables under the hood caused this to happen. I don't want to be taken advantage of when I take the car in, so should I look for things like this first?

The loose gas cap is a quick and easy check to perform, so try that first. The service engine light will remain on until the next "cold" start.
I would also recommend visiting your local Auto Zone and ask them to scan your car for trouble codes. They offer this service free of charge, write the codes down and respond back, I can let you know what they are and mean if you decide to have a technician fix the issue.
Good luck, let me know.
Regards,
