Coolant Level Low?

For awhile now, when I start from cold, the DIC gives me a coolant level low warning. I've regularly checked the level, but it's fine. I figured I'd just replace the sensor, but I can't seem to find a part number. Any ideas?

Also, everytime I put a fuse into the slot for the interior lights, it lasts a varrying time and then blows. Any ideas for fixing this?

Pull the connector from the Coolant Level Switch ( bottom of surge tank). Connect a jumper wire between the 2 connector pins. This will simulate a full coolant tank.
Can't help you with P/N, but you can at least verify the switch is the problem.

Fuse problem could be a lot of things, are you using the proper rated fuse.

I used the extra fuses that came with the car. It's strange. It started lasting 3 weeks, then 2, then like 4 days, and now it pops instantly.

I would at least start by taking out the bulbs, & seeing if the fuse still blows.
While your taking out the bulbs, check for pinched wiring.

Did you get the car scanned to see if there are any trouble codes? Autozone or Advance auto(and some others) should do it for free. I would call them first to see it they offer this service.
