Replacing the dimmer switch

[Hooky]

I got to work this morning and my low beams don't work. The high beams do so I imagine it is the dimmer switch. My rig is a 1988 Chevy S10 Blazer. I looked on the web from here at work and learned the dimmer switch is on the lower column on the driver's door side. My question is this; if you only had one arm like I do, is this something you could do yourself? I'm not sure about any possible clip connectors that might take two hands, or perhaps other two hand issues. I'll have a closer look when I get home tonight but wanted to get a "preview" of what to expect from you guys.
