MG ZR PROBLEM

2002 MG ZR • 75,000 miles

My blower works every now and then and only on 3 and 4 speed what part do I need to be replacing the motor or the resistor?

It very likely could be both. Motors that have excessive current draw burn out resisters. The on/off problem leans toward a motor but the missing speeds point to a resister.
