I have to add power steering fluid every time I fill up with gas. Not quite empty, but have to about 3/4 bottle. A mechanic told me that I need to have the "power steering pressure switch" replaced. Does that sound like a legit diagnosis?
I have not been able to find a replacement part for power steering pressure switch. can I buy just the switch or do I need to buy an assembly that includes the switch?
Thanks,

PS pressure switch is #33 on this picture. Follow the high-pressure hose from the PS pump.

If you're not sure of his diagnosis, then follow the hose & find the PS pressure switch.
See for yourself whether it's leaking? If not, then you have to FIND the leak first before you can figure out how to fix it.
