Power steering pump is making noise and it's harder to turn than usual. Is the pump bad? It was 24 degrees below zero yesterday and today.

Are you sure that you don't have power steering? It sounds to me like you have a leak in your power steering and low on fluid. The battery light is usually an indication that your alternator is not charging.

If it has become really hard to steer, that could be the problem. You will probably need to replace the power steering pump. However, if it has slowy become harder and harder to turn, (especially if it has/had a whining noise) then there is a good chance it is just low on fluid. Check your resevoir. They are USUALLY found closer to the driver's side, under the hood.

It could be the fluid (you need to gain access to the engine below the convertible top cover), or it could be your power steering pump going bad.

could be the power steering pump itself. If it has a bad bearing it will do that. Especially when you turn it makes the steering pump work a lot harder.

replace the power steering pump and check for any other power steering leaks (bad pump , low steering fluid )

it sounds like your power steering pump may be going bad and may need replaced

If the fluid is full than the sound is normal for GM when it is cold. You can try flushing the power steering system and adding an ounce of "Seafoam Motor Tune" to the power steering system after the flush is complete.

This may help with the noise.

Replacing the pump in an attempt to resolve the noise may make the condition worse. Aftermarket pumps are notorious for making more noise than the original pump. A new O.E. pump may be fine until it gets cold and then it may make the same noise.

Hello, from the sounds of it your power steering pump is going bad. Two things to check is one, pull off the cap and smell the fluid to see if it smells burnt. If it does you will need to change the power steering pump. Another thing to check is to make sure the belt is good and snug that runs the pump, the noice could be the belt slipping. You may need to tighten it or change it depending on how it looks. I'd check the belt first as that is the cheaper fix.

Make sure that the belt is not glazed and slipping on the pulley - they should both appear to be turning at the same speed. There is a chance that you have burned up the power steering pump and the noise you hear is the bearings complaining about the lack of lubricant they incurred.

check for leak in power steering hose by taking cap off the power steering resevoir and than starting car, wait 1 min, turn wheel all the way left and than all the way right. do this about 5-8 times slowly over 3 min or so. turn car off, than observe fluid in resevoir. if you see lots of bubbles after 30 seconds or so, you have a leaky hose. air in the system makes the steering pump groan and moan and vibrate. if the pump is not bad, than change the hose and clamp. just fixed mine yesterday.  also buy a quart of 11s pentosin power steering fluid (green)...
