So I just got done replacing pitman arm, idler arm, and 2 ball joints on my 2003 blazer 4wd, and now my power steering doesn't work. It worked fine before and I connected everything properly, added power steering fluid as needed there are no noticible leaks I'm stumped. Thank you

 

Did you put the serp belt back on? Did you raise the front wheels off the ground and cycle the steering wheel lock to lock countless times to bleed air out of the system? I don't think the lines can be crossed but I don't remember for sure so it's probably a good idea to check that as well.

 

yes did all that the only way to cross the lines is by really trying hard to do it. I've triple checked everything I can think of. Just seems too random to be the pump itself. Gonna try to flush it tomorrow. The fluid doesn't seem all that dirty but won't hurt to try
