In fuse box under hood, there is a 30 amp fuse. Do you know what it is for. jeep will not start. Replace fuse it tries to start or will start, but immediately, fuse blows and truck dies. Replaced relay for Fuel pump. Still does the same thing. Gas coming from fuel pump. Any suggestions? i feel that if I could find out what that fuse is for I could locate the problem
The 30 amp fuse is most likely for your starter. Check that the red thick wire (could be black as well) leading to the starter and starter solenoid is properly attached and is not touching anything that would short it out and therefore blow the 30 amp fuse. The short may even be inside the starter in which case it will need to be replaced or repaired. Hope this helps.

The fuse box is beside the battery under the hood. The fuses and what they relate to is marked under the lid of that fuse box. Use same size fuse if it needs replacing. If in doubt check all the 15 to 30 amp fuses.
In some Jeeps the fuse controls the transmission control relay in the power distribution box. Replace the fuse. If it blows again, there could be a short in the power distribution box or the writing between the power box and the control module.
I would start with the Fuse Box under the hood. Start by pulling the Fuse's 1 at a TIME!! I have done it befor time & time agean. It's probley by the Battery. It's a black box that has " Main Fuse " or something alone that line. There just like the Fuses under the Dash, BUT BIGGER! They can be hard to tell if they blew. I have done it so, much that I know. If it's not that I would check the Fuse Box in the Dash. Jerry Dunn
First check all your fuses in both the under hood (60 amp) and right rear (10 amp) fuse blocks. Remove the low speed fan relay (in the under hood fuse box) and install a jumper across terminals #30 & #87. These are not marked on the box, but you will find these numbers identifying these terminals. With power at the #30 terminal, installing the jumper wire will send power directly to the primary fan. The fan should now run, if it doesn't, check it's ground wire, if that's OK, replace the fan. Charlie
There are a total of 5 fuses for brake and abs functions 3 in central fuse box on the drivers side inside truck fuse #9 - 7.5 amp fuse #10 - 10 amp and fuse #11 - 7.5 amp then there are 2 big fuses under the hood in the main battery fuse box next to the battery fuse # 6 - 50 amp and fuse # 28 - 30 amp
I don't know on the Grand, but our Cherokee has a water valve right by the firewall on the heater hose to control the heat. Not actually a fuse as it is heated by the coolant running from the engine, but apparently there was an issue with some s*&t heating systems. What is the actual problem you are having? as this 'fuse' may actually not exist.You may need to simply flush your radiator, replace the coolant after checking near the firewall for the valve that lets the hot water flow through, This may be the problem?
