Remove the headlining then squirt some foam filler behind the support bars ,i think they may be flexing causing the noise as this sort of fault is common the rover 75

Does any one have any suggestions? THANK YOU!

SOURCE: 99 eldorado. trunk and gas door pop open

There is corrosion at the positive battery cable and the terminal is probably  about to fall out of the battery. Clean battery terminals, replace bolts and spacer if applicable and recommend battery replacement

HI. This will be an electrical issue with the engine CPU. You are essentially flying blind without the codes that are present and they need to be extracted with a proper GM certified scan tool device. The TC(traction control) light and Battery light are a strong indication of a weak battery or TCM module damage. That will be the first initial diagnosis, but with that said; Your engine CPU is actually initiating limp mode as well. This will occur if there are major sensor malfunctions present within the engine assembly. Limp mode is basically triggered when these symptoms exist with this particular vehicle. It is induced to protect the engine from further damage. It will shutdown certain cylinders down to reduce HP.

This vehicle will need the services of a competent mechanics or a certified GM dealership. The codes must be pulled, asap. If you have the codes now, please post them so that i may analyze them and provide proper direction.

2003 STS cadillac leaking water on both driver and passenger floor boards

It could be the sun roof. It also could be clogged drains from the sun roof. It may also be door seals Leaking. It could also be leaking around the bottom of the windshield. A good way to narrow it down is to get inside the car and have someone spray the outside of the car with a water hose. while you look for water leaking inside of the car. If it does it while the ac is on may be a clogged ac drain. however it usually just leaks on passenger side when it is that. well good luck.

Leaking water

Yeah ford would just replace it , You need a company that installs sun roofs they may well have just the seals for this sun roof , I would google sunroof installers in you area and see if there is one local who will fix this . I would say this is also not helping with you other problems .

Sunroof blocked drains

the drain holes are located at each corner of the sun roof carrier. you will need to open the sun roof all the way to be able to see the drain holes. the drain pipes run down the A and C posts of the vehicle. [A post front] [C post rear]. the easiest way to clear them is to use a flexible piece of cable pushed down from the top. if they are not blocked, the pipes may be off on the under side of the sun roof carrier. this usually happens if somebody has been doing panel work on the vehicle and forget to reconnect pipes. to rectify this you will have to lower roof lining. pipes just push on.

02 silverado gas tank popping noise after startup & shutdown

It could just be the heat shield around your exhaust expanding and contracting again when your engine cools down. Sounds like a tin can type of popping noise?? If it is that's the heat sheild from the engine that protect's the spark plug wire and around under the truck cabin. Good luck and hope you find where the noise is coming from.
