G6 GT hardtop will not go up, Houston 2 yrs now

What model and year? Maybe we could help each other if we know who the convertible owners are in one thread
I have a gray 06 GTP convertible with approx.56000 miles
Thanks
Have you received any help with the hard top? I think we all should file a small claim against GM for just leaving everyone hanging? [email protected]

Lube all the joints on the arms but before you drop the top make sure you have enough fluid in the hydraulic reservoir (remove rear panel in trunk on passengers side. It is the white plastic thing with a copper colored fill cap on top and a MAX line on it). I made the mistake of lowering it on low fluid. Then it would not raise. Keep in mind nothing else was wrong... I had to remove the trunk lid, back seats, take all of the pins out to manually lift the top - it is not light and requires 2 people - then put it all back together to find that it seems to have an error code that I need a Tech2 to release. I am not going to pay a dealer but bought an emulator and have a 32bit laptop to run it on thank god since it does not work on 64bit like most now are. So maybe, this will have only cost me about $128 for the emulator, $29 for the fluid (it HAS to be GM88901975) and about $35 in tools by the time it is all fixed. Not to mention about 4 days of crawling in and out of my car for hours adjusting things and cutting/bruising myself up. My neighbor actually asked me what the deal was with me and the car on the 4th day. Whatever you do make sure there is fluid in the stupid reservoir and don't count on dealers or online material to be able to help you either. Every time I think I have located the last mirco sensor there is another one and almost all are difficult to remove if you have to replace or in my case test them. The dealers around here cannot fix them so any error message they blame it on the controller which they claim you cannot find now that Pontiac is out of business. Not so... they just cannot fix these things. My advice is learn how it works before it breaks on you unlike me!

Dealers are retards! These are all simple sensors. You could replace them with many aftermarket ones but that fact aside... there are a lot of sensors and the reason your trunk will not work is because by default your top is error state so until it is cleared by a Tech2 the computer will not allow it to open. The key here is fix the top the trunk should work afterwards. There is most likely a message of "Top not Secured" on your radio screen. If the top is secured, then it likely is an error to be cleared by a Tech2. Also, the hydraulic reservoir in the trunk on the passenger side under the plastic inner fender should be to the max line. Only use GM 88901975 on it! I am going to try an emulator for the Tech2 and see if I can access the sensors on mine.

It's great seeing all of these mechanical folks fixing their own cars. That takes a lot of know how! Well, I will never be fixing any car. I live in Illinois, across the river from St. Louis. If there is anyone out there within 100 mile radius or so from St. Louis, sure would like to know. A good mechanic who would take on the repair of my convertible. Sure would be nice to have that car "sun and fun" usable again.

New member: 2007 G6 3.5L white convertible with 56K miles. Oil pan appears to be leaking. I just replaced the oil filter adapter gasket which I now think wasn't leaking.

Then you'll have one VERY big multi-page thread with dozens of subjects and it will be difficult to sort through.
You'll get the best fastest reply if you post your problem in a new thread instead of hijacking an existing one.

My husband making me get rid of my 07 G6 GT convertible. Everything seem to be going out. Examples include cruise, steering wheel controls, pedal adjustment, hard top hydraulic. Windshield washer, seat heater just to name a few

The oil pan leaks on many of them from what I have seen. It is a very intense job from what I have been told by my friend who is also a mechanic at midas. You have to un-bolt passenger side engine mount and lift it a certain height to clear the pan out from under the car and before that remove the convertible structural supports. There are other things but mine doesn't leak too bad so I am saving it for another time. The few things I have done to my engine have always been way too difficult. The waterpump, the thermostat before that. Not fun at all! Very tight room and being careful not to break something else is priority!

Agree! I wrote to a class action attorney and asked about it. They said no. You could try and see what response you get. Let us know! Good luck, really think that GM owes us all something.

On the lighter side, the battery in these cars is among the easiest to replace of any I've owned.

Sadly, the truths that should be self evident of anyone who owns one of these cars (or wants to) is that (1) They're all at least 10 years old, (2) Pontiac has been gone for 10 years, (3) Any GM technicians trained on these have long since moved on or retired, (3) A few parts may exist in the GM system but once they're gone, they're gone and your/our main source (for other than common mechanicals) becomes "Pull-N-Save" salvage yards. Reality bites of course and it's pretty much the same for any car 5 years in once the platform has been discontinued, let alone the whole line or make has been dropped.

I'm old and this will likely be my last special interest car. With the goal of educating myself I bought one of these:
https://www.ebay.com/itm/Pontiac-G6-2005-2009-Complete-GM-Service-Body-Workshop-Repair-Manual-DVD/143144085564?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649

GM's documentation has evolved through the decades and is geared to the technician and features cryptic line drawings rather than clearer photos. This disk has as much information as likely exists, but it's clunky and not for the faint of heart. It also requires a fairly recent computer and installs a Virtual Machine running an instance of Windows XP (remember how old these cars are). It does work though and there's a ton of information and (bonus!) the embedded links to related topics work.

Since everything since OBD was first developed requires a scanner, I also bought one of these:
https://www.ebay.com/itm/GM-General-Motors-Diagnostic-Scanner-Code-Reader-ABS-SRS-SAS-Scan-Tool-Vident/123411631610?ssPageName=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649

I haven't received it yet so it's usefulness hasn't been proven, but the price point made it interesting to me as opposed to the GM Tech II. I'll let you know.

Good luck everyone. - Mark

Thank you for this post! I'll look into the eBay links you shared as well. I've got an '07 hardtop convertible and was just told I have a front main seal leak and need to replace the front struts. Has anyone done these at home? Any advice? I'm also trying to chase down a door rattle that is driving me nuts!

I replaced the front struts on mine recently. It was time consuming but not too difficult. The main bolts by the knuckle were a pain to hammer out. Remember to leave the nut on the end of the threads to protect the bolt as you pound it out. The 1A Auto videos are usually quite helpful -

White G6, 130000 miles on it, the top still is working. However, the alignment seems to be off. Machinists told me there is nothing they can do.

I'm dealing with mystery coolant loss. No visible leaks but having to refill the tank often. Heater isn't working, guessing that's related. AC works like a champ however! Any ideas?
