I have a Lift Gate question

I have a 93 Yukon, 2dr and my question is... Is opening the rear glass is a two man operation?

I can unlock it from a button on the dash, or, a handheld remote. When the actuator lets go of the glass should it pop open a little bit, or do I need to open the glass while pressing the button. I would think that you would press the button and then walk to the back and open the glass. I have to hold the button until the glass is opened. Is this normal? I have searched the site and could only find answers for the rear glass not unlocking at all.

Thanks in advance!

ya it should pop open a bit. i can hear mine when it pops. one time when the tail gate wasnt shut all the way and i closed the glass, i had a heck of a time getting it open again.

Thanks for the reply.
I talked to a guy yesterday that I ran into with a 92 blazer that he's had since new... He said that his stopped working a couple of years after he bought it and never got around to getting it fixed. It still opens, but he has to use his key.
