Fuses

Print
The fuses are of the miniaturized (compact) size and are located on a fuse block, they provide increased circuit protection and reliability. Access to the fuse block is gained through the glove box opening. Each fuse receptacle is marked as to the circuit it protects and the correct amperage of the fuse.
REPLACEMENT

1. Pull the fuse from the fuse block.
2. Inspect the fuse element (through the clear plastic body) to the blade terminal for defects.

When replacing the fuse, DO NOT use one of higher amperage.

1. To install, reverse the removal procedures.

its really a job for an auto electrician

to DIY needs a replacement fuse block from a wrecker
with a bit of the loom wiring as a colour guide
then you rewire one fuse/relay connection at a time

My info shows the ECC fuse 10Amp powers the Lift gate lock relay. this is the only Info I have so far. the ECC fuse is located in the instrument panel Fuse block. That fuse block should be at the left end of the dash. You have to have the drivers door open to access it. the fuse will be on the left side of the fuse block bottom corner just above the 25Amp circuit breaker for the LT doors. when you remove the fuse make sure the connection in the fuse block are not heated looking or that the fuse block itself is not melted looking. If so you have a loose connection there. you can try to close / tighten the connection with a small pick. bend the connection point closed so it will be tighter in the fuse when you install the fuse.

REPLACEMENT

1. Locate the fuse for the circuit in question. NOTE: When replacing the fuse, always use a replacement fuse of the same amperage value. NEVER use one with a higher amperage rating. On some vehicles, you may have to remove a cover for access to the main fuse block
   The fuse panel cover has a label with the fuse designations on it
   
   
2. Check the fuse by pulling it from the fuse block and observing the element. If it is broken, install a replacement fuse the same amperage rating. If the fuse blows again, check the circuit for a short to ground or faulty device in the circuit protected by the fuse. Locate the fuse which needs to be checked . . .
   . . . then pull it out of the fuse block

   Fig. 2: After you pull the fuse from the block, check the element
   Fig. 3: Visual examination will reveal a blown fuse, but it should not be replaced until repairs are made
   
   
3. Continuity can also be checked with the fuse installed in the fuse block with the use of a test light connected across the 2 test points on the end of the fuse. If the test light lights, replace the fuse. Check the circuit for a short to ground or faulty device in the circuit protected by the fuse.

hello there:
the gap for you're gmc should 0.45
hope this is help full

The fuse block is located under the instrument panel to the left of the steering column. The fuse block should be visible from underneath the steering column, near the pedal bracket. If the panel is not visible, check for a removable compartment door or trim panel which may be used on later models to hide the block.
Each fuse block uses miniature fuses (normally plug-in blade terminal-type for these vehicles) which are designed for increased circuit protection and greater reliability. The compact plug-in or blade terminal design allows for fingertip removal and replacement.

Hope helped (rated this). Good luck.

The "fuse block" is simply the plastic housing (typically square) that all the replaceable fuses are inserted in.
There should be all the fuses plugged in and in one corner is the flasher ..

if you look in your fuse block there are multiple little fuses and larger block fuses, if you look at the diagram about the fuse block find out wich large block fuse is the one to make your lights flash and replace the defected one with a new one

should cure your problem
