Rear hatch window will not open

Hi everyone,
Today I pushed the hatch button and nothing happened.  I heard a click but the rear hatch window did not open or release. I have been using the hatch vent so I wonder if this little device has messed up something internally? Any thoughts?
Thanks

It's possible that the vent latch messed up the hatch latch, but I think it's the hatch itself...have you tried having someone hit the release while you push/pull on the hatch latch?


Remember, there's no place like ~ ;)

There's really nothing the vent latch can mess up. The clicking is the solenoid releasing the latch so that's good. If your struts are like mine (original) they don't operate smooth enough to always push the hatch up and often need a little help to get started. So, try as suggested previously. If it stays locked, then the fun on your back begins. Mine's open at the moment. I can get you a picture if it doesn't release.

Good suggestions.  I pushed the button while my husband pulled on the vent latch and nothing.  It wasn't releasing but it is still clicking.    Yep, my back has been getting a workout unfortunately. I have been using the manual release cord. Cry

These may help. Perhaps the solenoid is detached but not because of the adapter. I don't think the solenoid will click if the switch is bad.

Thanks for the pics. I think the solenoid is fried.   I took it apart and used the manual to see if the plunger went in and out.  Sometimes it became stuck and I had to push it back in.  When I push the release button it does nothing.  Another fix to add to my list.  It won't stop me  from driving so.....it goes to the bottom of my list.  Big smile

There's a hatch release relay, too. Something to be aware of and check.

IMO..it sounds to me that the switch and the relay are working. if either one was bad the solenoid wouldn't even click. i would go for a new solenoid too.

I recently experienced the exact problem on my 88 Targa.  While I pushed the button with a long wooden dowel, standing behind the car I could hear the relay click but the hatch lock would not activate to the open position.  After a couple of clicks I located the hatch relay about 6 or 8 inches to the right of the hatch mechanism  It would open manually with the safety cable so I knew it wasn't the mechanical part of the switch. I hunted down a used hatch assembly on Ebay for about $45.00 and now it works every time with the console button and the release switches on the doors. I had already replaced the strut shocks with new ones but the hatch would still unlock even if the old shocks would not lift the hatch to the fully open position.  Hope this helps. Good Luck!
