    how cold is it? on my 2005 yukon xl I had the same issue when it was -15f (-26C) here. The only door actuator that worked was my driver side rear door. I could see the others trying to work, they just did not. As soon as I put the truck in my garage and it warmed up they all worked fine again.

    I have a similar issue with my 08 Silverado.. but it's both of the passenger door lock actuators that aren't working properly. they work during the "winter", but our "winter" lasts all of about 10 days.. and that's spread out over the course of 4 months. I've heard this is a common problem with my model pickup though, which means it probably doesn't have much to do with your issue haha. sorry

    I have a 2008 Impala that experienced a very similar issue: I had 3 of the 4 door lock actuators fail over time. When they started to get flaky, they'd work if the outside temperature was below 70 deg. F., but would stop working if it got too warm outside. Eventually, they'd stop working entirely. was a good place to find replacement OEM locks at a good price. Not sure on the Express vans, but you can't use a generic actuator on the Impala. I'd bet that the Chevy vans are the same way.
