Dead battery and can't open hood
I was able to put voltage at the fuse box, the dashboard came on but the trunk
or hood levers did nothing
DId you try using a power port tap hooked to an auxiliary power source?
Open drivers door...in the foot well where your left foot would be is a removable fuse panel cover. Remove it, and read the instructions, which tell you to pull out the "dummy fuse" which is a + terminal, attach a + jump to it, and a - jump to the door stop... You should then have power for the hood switch, to get to the battery.
I thought the 98 car used a cable operated trunk mechanism? Do you have a lever type or electrical switch type trunk mechanism? It that's the case, you need to try the emergency cable release in the front passenger wheel well. You need to pull the plastic liner out then look for the cable release, its normally near the back of the headlight. You can also buy a cheap battery tender thing that plugs into the cigarette lighter that should give you additional power to open the trunk
I put voltage at the fuse panel, got the dashboard illuminated, fan working but the hood and the trunk levers would not work. Is there some lock? Tried with the switch on, hand break on...nothing.
You have the cable operated mechanisms, it does not use electricity to open the trunk. The problem is likely something else, either cable or latch mech. Try the emergency cable I mentioned in my last post.
