Nice looking car. I looked back at previous posts and see that you've had it a long time! I'm sure you've kept it garaged...so no chance of water in the trunk. I saw this early post from you:
I don't know exactly why they were not popular and did not sell. I purchased my 2006 in 2008, brand new and never titled for almost 1/2 price - the dealer flew me to them and I drove it home - bought it off EBay - best purchase I made for a vehicle and it's just a toy for me which is exactly what I wanted. I love it. I will be glad when the payments end and I get to enjoy it for the many years to come but I don't mind paying for it at all!

1. You said in your first post here that you had just gotten the car out of storage. You said "it is running great".

So, did it start right up? Any possible battery issues after being in storage? You didn't clarify that.

2. You said in your first post, "it appeared to start and then beeped and stopped. When I unlatched it and pushed it up the windows went down, and when I pressed the button it started to go maybe a bit and then stopped, and that was that - no more movement - just beeping." In your second post, you said "I did not hear the latch, unlatch, nor did the back window come up."

So, did anything move at all on the top? What is it doing today, if you go through the same sequence for lowering the top? You are running the engine when you're trying to lower the top, aren't you?!

3. I would expect that the top would operate with the fluid level at the "minimum" mark. But then again, the question is how did it get down to the minimum mark. The fluid isn't consumed. It can only leak out.

4. Is it a coincidence that your remote does not lock/unlock the car? I'm still wondering about that. You said "when I'm trying to lock the car from the remote, the hazard lights flash 4 times - the locks do NOT lock."

Are there any other electrical issues that you can observe? Does the dome light come on? Does the siren work? I just went out and pulled Fuse 9 out on my Crossfire. (Some people say the alarm might sound if you do that, so be ready. My alarm is disconnected.) With Fuse 9 out, when I try to lock the car using the remote, I see the hazard lights flash 4 times and the locks do not lock, just like you said. My dome lights are also out. However, my top is fully functional. It went down without a problem with Fuse 9 pulled.

Sorry to ask more questions. Just trying to learn from your symptoms. I had top problems when I bought my '05 three years ago. I replaced two cylinders to get it working again.

Hopefully, adding fluid will solve the top problem. And maybe after that, you can start checking a few electrical possibilities related to the remote not locking.
