Drivers's sliding door wont open :(

[ottawagirl]

I am new here and desperate for some advice. I have a 2007 Pontiac Montana sv6 and yesterday I filled the gas tank on my way to pick up my kids. When I went to load the kids into the van, the driver's side sliding door will only open about 3 inches before it stops. I am only 1 week outside of my warranty and scared that the fix will be ridiculously expensive. Any advice on what this might be and how I could possibly fix it?? please!?

Look in your owners manual for the "door reset procedure" I hope that is all it needs . Good luck keep us posted
