Hissing when locking / unlocking
Hi everyone,
I am new to the forum and I was hoping you could help me. My wife’s black 2004 Crossfire coupe has developed a strange fault and the dealer has been not very helpful. When you unlock the car with two presses of the keyfob you can hear a hissing air noise from the boot area outside of the car and it is even louder insider. It only lasts for around 5 seconds. Everything unlocks fine. When locking the car it takes around 30 seconds for the little shaft to slide across and lock the fuel cap. If you don’t hold the fuel cap in place until it locks then the shaft will miss it and the fuel cap will not be locked.
Our dealer charger over $1,000 to replace and fit a new pump which made no difference. Now they reckon this is something to do with the fuel cap (motor?) is causing the failure. The knowledgeable technician is off sick and we have no faith in them as they couldn’t solve a trim squeak and ended up putting the luggage cover hooks on upside down. 
Anyone have any ideas on what could be causing the hissing issue?
Many thanks,
Chris
