Windshied Washer Pumps...

Anyone know if there are 1 or 2 windshield washer pumps in a 2011 gmc sierra 1500 5.3 4wd?

Just one

I was hoping there were 2 thinking one for each side, but I am having problems with not enough liquid on the windshield on the drivers side, I have replaced the whole wiper arm, blew air back through the tubing, there are no breaks in the line, nothing leaking, so I don’t know what to try next except a new pump. it’s been a minute since I looked at it but seems the longer run of the tubing is to the passenger side but that side seems to get more liquid.

Remove the washer nozzle from the arm & hose. Soak it in some CLR cleaner & reinstall....

I installed a new wiper arm that included the nozzle. Still the same problem.
