The problem may be a short in the system. A blown fuse is an indication of somthing in the control unit that is wanting to make it burn out so instead it burns out the fuse as a saftey measure instead of the control unit. A short can be really hard to trace at times, what you may want to do is take it to your nearest auto repair shop for an electrical diagnosis. Also if you have a multimeter you yourself can try and find the short if you know enough about electrical devices. If you'r looking for a repair shop, try Pep Boys, they usually do very good work and would definetly be able to take a look at that for you.

Hope This Helps!

Try unplugging the blower motor, heater control unit and blower motor resistor. Replace the fuse then reconnect the items 1 by 1 and see what pops the fuse.

Unusual the dealer can't or won't find the problem.
A mechanic would check everything in that circuit for shorts to ground.
Was the fuse blowing before the alternator and battery were replaced ?
Based on the wiring diagrams I would vote for a defective alternator.
The 10 amp fuse number 8 powers the cluster which also goes to the alternator. If the alternator shorts out internally it would blow that number 8 fuse and take the cluster with it.
The other circuits you mentioned are controlled by the key switch but are fused after the switch. So if the switch was causing the problem it should be blowing a 40amp fuse.
I would probably take the alternator off and have someone else test it.

No I think there is something else on the circuit which is bad, and you replaced the wrong thing. In other words the heater controls were not blowing the fuse and the fuse box is doing its protection job, at least was until you melted it from putting the wrong fuses in it. Adventures such as this show why it sometimes saves time and money to simply pay someone who knows what they are doing to do it right the first time. Electrical systems today are so complex that someone with all the info and tools at had is required to fix them.

On the back of the panel you will find one side of the fuse is connected to 12 volts, the other side has some connectors, or has one connector wire which takes the 12V to a set of connections. You have to disconnect each of those connections, one at a time, and replace the fuse until you find the one which actually has the component which is drawing too much current for the fuse. Then you either live without that component or go buy another one.

check the AMPS for all your fuses sometime a low amps fuse in the wrong slot can blow otherones. also sometime you can increase the fuse that keep blowing. try that first if that do not work you might need to run and electrican test on your fuse box to check if you have a short. also check your fuseable link on the fuse panel under the hood.

The ECM1 fuse blowing usually indicates that the fuel pump wires shorted inside the tank. If you drop the tank and remove the module, you will probably find the insulation burned off the gray pump wire.
