Ok...when it was warm it worked fine...I did notice that the squeeze handle would get stuck in the open position....it feels like it has too much grease in the mechanism to release it sometimes. So today...its COLD out..the handle was in the open position and I hit the unlock button in the cab and I walked around and I figured that I should just be able to lift up the rear door...NO GO! so has anyone experienced this before? if so whats the "fix?" thanks in advance....Garth
