My 1997 Chevy venture power steering won't let me turn it. I put power steering fluid in it but it's still hard to turn my steering wheel

Here's a video,it may have the same power steering pump as your's. Check Power Steering Level Pontiac Montana 1997 2005 2004 Pontiac Montana...

if it is electric power steering pump and hard to steer then the motor for the pump is not operational
check relays and fuses

With engine running, steering turned hard right or left, can you see the fluid churn in the power steering reservoir? If not, maybe one of the power steering lines is blocked?

I just wanted to add, with some makes and models. With everything off, I remove the power steering belt. I take the return line loose from pump, aim into container, rotate the pulley by hand, see if any fluid comes out of return line? The return line should be low pressure, usually held to pump by hose clamp. The high pressure line has threaded fittings.

ck. p.s hoses 4 leakage fill pump have someone turn wheel back & forth look 4 leak

Have you checked the power steering fluid level? The reservoir for the fluid will be at the front of the engine, where the belt runs the power steering pump. If it's low or out add a little power steering fluid till full, then start car and slowly turn wheels back and forth from stop to stop-not too ******* the stops (when the steering won't turn further that way...that's what I mean by stops)....Turn wheel one way full travel, then reverse and turn the other way. Check the fluid level again, and add as needed.
If fluid is not low, the belt may be too loose to make the power steering pump work, or you may have a bigger problem that needs professional attewntion.

Hi hope I can help.
First check the power steering pump fluid.
Also check your belt to the power steering. make sure it is not slipping.
After checking both of these and you still have a problem .
you will have to replace your power steering pump.
Hope this helps FixYa

Please check the fluid level in the power steering pump. After putting on a new hose the fluid may have traveled through the system and you may need more fluid.

sounds like it is out of fluid if you fill the fluid then turn the wheel to one side and hold it you will build up pressure and see where it leaking from.
