If they are stock, there is a second switch on the light/turn signal stalk. I don't have any picture of the stalk and can't go take one until later tonight.
Since you just bought the vehicle, you may want to replace your
In-Cabin Air Filter (if equipped). Many people forget these exist and as a result never change them, resulting in nasty smells or poor A/C performance sometimes. I would also pull through your local dealership and see if there are any recalls not yet done on your Pathfinder. There is also a
new recall regarding the driver's side strut rusting which will take effect around May 16th, so perhaps wait until then to visit your local dealer.
And yes, you will need both if you are missing both. For future reference, there's a small edit button at the top right corner of your posts, so use that instead of double posting within such a short time span next time.
There is also a potential issue with the screws securing the power valves (aka butterfly valves) becoming loose and possibly backing out far enough to be sucked into the engine and potentially cause major damage. This is similar to a recall for 2004 Sentras and 2004-2005 Altimas with the QR25DE engine, but Nissan has not issued a recall for this potential issue for our Pathfinders as it's not as widespread an occurrence as on the recalled engines. The solution is either to remove the upper intake manifold and put some threadlocker (Loctite) on the screws yourself, or have a mechanic or the dealership do it. The dealership will charge around $280-300 to do this I believe. Like I said, it's not an extremely widespread issue for us but until you get threadlocker on those screws, you aren't guaranteed to be unaffected. I've got 123k on my 2001.5 PF and no issues yet, but I haven't put threadlocker on my screws yet, primarily because I stripped some of the bolts/nuts that hold the upper intake manifold on and I need to obtain replacements now.

Just informing you, as it's something you really should be aware of especially as a new owner.
