Rover 75 aircon startup delay

QuestionMark · 20th April 2017, 17:24

Hi,

This has been annoying me for a while, so I thought I'd ask about it. I can't seem to find any other threads about this, so if you know of any, please link them

The problem is that there's often a delay from when the car starts and when the aircon (ventilation fan) starts. The delay can vary from a few seconds to a few minutes. Other times there's no delay at all. This is very annyoing, especially since my car is always full of condensation (and, if below zero, ice...)!

Pushing different buttons (auto, demist, etc.) doesn't get the fan started either.

I haven't noticed any correlation between outside temperature or engine temperature and a/c startup. Once it starts, it works perfectly.

If relevant, I have the two speed radiator fan with gold resistor mod, and the radiator fan works just fine as far as I'm aware - the low speed activates immediately with ignition + demist.

Any ideas?
