Sounds like you need to invest in a high pressure test set! 😀

I have replaced both the rack and pinion and the pump. Repair last maybe a day or so and then i lose power steering again. What can cause this?

HI Steve i have a 2009 Acadia .. i got the compressor replaced and condenser cleaned... the ac cools when u drive but when you stop or slow down .. the ac stops cooling. any suggestion how can i get it fixed

You never checked the electronic power steering fuse.
