Power Lift Gate Blues

2002 Grand Caravan, Power Liftgate opens OK when weather is warm..just unlatches when a bit cool to cold and stops. I have tried to help it raise with no success. Any one with similar problem and fix.
Thanks

It's possible that the seals in the lift gate support struts are weak and allow air & moisture inside the pistons. If this is the case, you will need to replace the two struts to get the gate to open on cool days.

I've got the same problem in my '01 T/C. I'm also unable to automatically lower the rear gate. I gave up on it pretty quickly. It's still cold here (35 deg. & rainy), but when it finally warms up, I'll see if it's a temperature related issue.

Is a support strut replacement fairly straightforward?

Thanks.

Refer to the Popular Mechanics article for strut replacement:

I own a '95 Voy and have no experience with automatic liftgate closure motors or mechanisms.
