Heater Fuse Issues - philpemberton94 - 06-01-2014
Hi guys, Im having some trouble with my blower fuse blowing on my 1.9TD Meridian, if I switch the blower on the motor will blow and then the fuse will pop after about 5 seconds, so i tried unplugging the blower motor itself and the fuse still blew. I disconnected the A/C and the blower stayed on for longer with no blown fuse, I then started to get smoke coming from the centre console and the fuse blew after about 10-15 seconds
I took the control panel off and saw that one of the pins on the plug had burnt, a diode had split and there was what appeared to be staining from the smoke on the white plastic that the circuit board sits in.
Could this split diode/ burnt out connector be causing the fuse to blow?
Or would there be a short somewhere on the blower loom that caused the diode/pin to get too hot? I have a new control panel on the way but don't really want to put it in if its just going to get ruined again! Any one know how to get the blower loom out? access seems pretty minimal on the drivers side, passenger side is ok, would it be a dash out job?
Any light shed on the subject would be greatly appreciated!
Cheers, Phil

Anyone??

at a guess the burned connectors has blown the diode and popped the fuse
the diode is a protection diode it will work without it but ,the electronic switch on the board is probably fried
i would go and try a new/secondhand control panel

Cheers pal
Is it possible that a short has caused the connector to burn or can it just happen?

loose connections burn plugs
shorts will pop fuses

Cut the diode out and it works!! Although the circuit is now unprotected, but it will do temporarily. It's not actually on the road yet as I haven't even passed my test but its nice to be able to see out of the windscreen for the first time since i've had it!
Cheers again mate, great help!
