95% of those fuses should have no drain at all. You shouldn't be checking it that way anyway. You should be checking total draw at the battery.
Here is the procedure.

You will need a digital ammeter and a jumper wire with clips on the ends to do this.
First rig any door switches so you can have a door open without triggering the interior lights and unplug the hood light. Remove one battery cable and attach the meter in series between the battery cable and battery post. Take the jumper wire and also attach it the same way. Leave the jumper wire on for at least 10 minutes to expire all the automatic timers. Now remove the jumper wire and read the meter. Anything over 50ma is too much draw. The way you locate this is to start removing fuses one at a time until the meter drops to normal level. This will be the circuit with something staying on. Determine what components are part of that circuit and check them individually until the problem is isolated.

So if there are several circuits that have a draw, there are several issues to look into, correct. Normally, does that mean that there are malfunctions to say a ignition switch or maybe even a blower motor or a multiple of items.
