power assist rear hatch opens but won't stay open. Cost to fix? on 2006 Kia Sedona

I am not sure if it is one of the two side struts or the single one. The motor works fine. I might be able to fix it myself but if not, any idea of the cost?

It's difficult to say without properly diagnosing it. Fixing it is the easy part. But not unless you properly pay someone to first diagnose why it is not working.
