Hi guys I might be just being a bit ott here but I’ve just put a new heater resistor in my cars heating was being temperamental. It does seam to have fixed the problem but I’ve noticed something since.
There’s like a cracking noice going from where the resistor is and if I push it in more it goes away but it’s in as far as the screw will let it so I can’t get it in any further
Anything to be worried about?

Cheers guys!
