Answer
Hi Cedric,

I'm sorry to hear that you're having car troubles, I'm going to do my best to assist you and correct your problem.

Let me first assist you with the blinker problem, as that is the easiest one to fix & correct. From the sound of what you're telling me, it sounds as though you have a defective flasher. The flasher unit in your car is what controls your blinkers, when the flasher stops working basically the internal relay of the actual flasher is no longer making the connection that it needs to make in order for the unit to flash.  The Flasher in your vehicle is a relay that is built into the fuse panel of the vehicle.  The flasher will probably be silver in color although sometimes they can be black. You can reference your vehicle owner manual under the fuses section, or you can reference the diagram directly under the cover on the fuse block to locate the flasher for the relay in question. If you cannot locate it please let me know, and I'll check my database and give you the proper position of the flasher on the fuse block.  Once you locate flasher, you can remove it and bring it to any auto parts store, and they will be able to give you a replacement one that you can plug back into the fuse block, and that should resolve the issue. If this does not resolve the issue we will need to go further into the diagnostic process, please let me know if the replacement flasher does not correct the issue.

As for your gas gauge needle, I will need some more information from you in order to properly diagnose, and fix this problem. Can you please explain to me what you mean when you say, "it was working for two days, then went out." Do you mean that the light behind the gas gauge needle is not working so it's not illuminated, or do you mean that the gas gauge needle is not working at all where you cannot see how much gas is in your vehicle.

If the needle is simply not illuminated, that is a simple electrical wiring issue that we can correct very quickly. However, if the gas gauge is not working at all to the point where it's not showing you how much gas is in the vehicle, that is a completely separate issue and will probably require replacement of the gas gauge needle itself.

Please let me know how you make out, and get me that additional information as soon as possible so I can further diagnose your problem. I hope that the information I provided is helpful to you and assist you in correcting the issues with your vehicle. Please let me know if I can be any further assistance to you.

Good luck, Thank you.
