What needs to be done as this may have been caused when the repairs were done previously is to check over the work that was done to see if any connections were left loose or damaged in any way needing reconnected or repaired.If a fault is found with any of the connections or wiring this will need repaired.Usually this is the cause here when work has been done previously before this fault occured.If this is all checked and found to be o.k. let me know so we can continue.

Hello, if you unplug the blower motor and measure voltage at the connector it should start off around 3.8 volts on low fan speed and go up slightly with each increase of fan speed up to 11..8 volts on high.
From what you describe the mofset is most likely faulty. On these vehicles I recommend replacing the blower motor and the mofset together as high amperage draw from a worn blower motor will cause the new mofset to fail prematurely.

I'll post the wiring diagram below from a sedona, which is the us equivalent of the carnaval.
You should be able to swap out the front mofset with rear for testing.
Sorry let me reupload it, you should see battery voltage on pin 1 and the module should vary voltage to the mofset.
