Late heater controls melting!

Recommended Posts

I had to fix my heater fan speed knob as the arm had got so hot it melted the plastic, this stopped it from fixin to the plastic part. Now ive fixed it ive noticed the metal parts still get very hot! Is this normal? It works fine but it cant be right!

urr no that sounds very wrong and dangerous......have you checked through your fuses to check that you've got the correct ratings?

Thanks for the reply, the fuse is the correct 20 amp one but ive only had the car 5 months and when i bought it i replaced many of the fuses as they were the wrong ampage, im worried now somwthing in the blower motor has been shorted and its drawin too much current. Everything works perfectly tho! It is very worrying as im not talking warm the contacts are hot! Can someone please stick their blower on four for a few minutes and confirm the contact plate or arm shouldnt get hot at all? Any idea on a fix please??

Im a wee bit worried, the one thing i can fix is a burnt out car!! :lol:

......make sure you have a good earth connection in the engine bay ... there should be an earth from the battery to the body and then again from the engine to the battery and body, any bad earth connections in this area will cause problems like this .......... my sister had a mini that had similar problems and that managed to turn the choke cable into the only available earth and that glowed damned hot !!!!!! :)

Hey guys, i finally got round to taking the car to bits and discovered something a little worrying!2.8l 24v Climatronic system.pdfwire1.jpg[/attachment:342d1]wire2.jpg[/attachment:342d1]

 

as you can see, the heat was a serious issue!

 

the previous owner has taking the feed from the full 12v fan line and spliced it into a cable which goes from the fan fuse box to the positive terminal of the fan motor. This 12v line should just go directly into the top of the fuse box!

 

I have no idea how or why it still works but it does. That explains the immense heat when the fan is turned on and the melting problem!

 

only problem is i have no idea where to start fixing it. Its davia AC unit so isnt factory. Can someone suggest a solution before i just start taking the fuse box bit appart!

Thanks in advance

Si

i think ive discovered the problem...

 

on the thermal fuse, is there supposed to be four contacts or five?

 

Ive been searching ever post for answers and in one someone says the golf only ha three speeds so needed three inputs to the rheostat and one output.

 

If ive somehow got the golf three speed one that explains why the previous owner just spliced in the 4 speed line bypassing the rheostat!

 

Can someone confirm this? a picture of your rheostat would be ace!!!

 

:D

Having dug out a pic of the corrado fan resistor pack i can safely say this isnt it!!

Any guesses what this has been taken from? Do any other VW cars have a four speed resistor pack like the corrado? I might go and raid the breakers at the weeknd!
