Morning kitchen faucet side spray

[jeffmattero76]

At one of my rentals I have a Moen kitchen faucet with a side spray, and that side spray is not working. This is an older (10 years or so) faucet, so the side spray is not the "quick connect" type. I swapped out the nozzle, and that didn't solve the problem. Any ideas?

At one of my rentals I have a Mountain kitchen faucet with a side spray, and that side spray is not working. This is an older (10 years or so) faucet, so the side spray is not the "quick connect" type. I swapped out the nozzle, and that didn't solve the problem. Any ideas?

Sorry. Should be Moen, not morning and not mountain (damn autocorrect)
