Hi there, my 2006 Zafira a 1.6 life model with 38000 miles on the clock is just causing me despair at the mo, the heater appears to be working but the blower's not, i've seen answers for the heater not working but the blower is, does anyone have any idea what this could be as the condensation on the inside and having to drive with the windows down in this weather is brutal? cheers in advance.
