* Is the steering difficult to turn at all speeds, or only at low speeds? This helps pinpoint the problem area. Difficulty at all speeds usually points to a mechanical issue, while low-speed difficulty often suggests a power steering fluid or pump problem.
* Is there any whining, groaning, or other unusual noises from the power steering system? Noises often indicate a failing pump, a low fluid level, or worn components.
* Is there any leaking fluid under the car? Leaking fluid is a common cause of power steering failure. Check the fluid level in the power steering reservoir – is it low?
* Does the power steering feel "spongy" or unresponsive? This can indicate air in the system, a failing pump, or a leak.
* Has the power steering fluid been recently changed? Incorrect fluid can damage the system.
Possible causes, based on common Grand Am power steering issues:
* Low power steering fluid: The most common cause. Check the fluid level and add fluid if necessary. Use the correct type of power steering fluid; consult your owner's manual.
* Leaking power steering hose or pump: Inspect all hoses and the pump for leaks. Look for wet spots, stains, or dripping fluid.
* Failing power steering pump: A failing pump will often make noise and may not provide enough assistance.
* Worn power steering rack and pinion: This is a more serious and expensive repair. Symptoms might include difficulty turning, knocking sounds, or a stiff steering feel.
* Clogged power steering filter: Less common, but possible.
* Air in the power steering system: Air bubbles can interfere with the hydraulic pressure. This often requires bleeding the system.
Before attempting any repairs yourself:
* Safety first: Always work in a safe, well-ventilated area. Power steering fluid is messy and can be harmful to your skin and eyes.
* Consult a repair manual: A repair manual specific to your 1994 Pontiac Grand Am will provide detailed instructions and diagrams.
* Consider professional help: If you're not comfortable working on your car's power steering system, it's best to take it to a qualified mechanic. Power steering repairs can be complex.
