I have a 2000 cadillac deville it has a brand new battery. It starts when it wants to will run for 5 days then won't start again there is a clicking noise comming from the fuse box under back seat. And fuse boxs also gets very hot where the relays are how can I fix it so it starts everytime

replace the relay , when a relay sticks like that , a good test is to slap it with something like the handle of a screw driver , see if it un-sticks , its not a fix , just a test . cheers'

I have a 2004 CTS. I know there are two fuse boxes underneath the floor carpeting in front of the rear seat. Remove the rear seat bottom cushion and pull the carpet forward and you will see them. Inside the cover identifies what fuse is for what function. Hopefully it is a blown fuse, otherwise my guess would be a short in the wiring some where.

The pressure they work within is usualy information on your radiator cap or owners hand book.Your thermostat should be a 180 degree but can vary The 180 is in reference to the heat required to open them so water can flow through and be kept at a more or less constant 180.There are other temp ranges for a wide variety of applications and 180 is the standard one for most vehiclesThe radiaor and water system is pressurised to lower the boiling point of the water The higher the pressure the lower the boiling point
