Many Vauxhalls have a cooling ECU, fitted in the grill area, it controls the logic of cooling/aircon fan use - they fail frequently.

There is no cooling fan control module on these.There are 2 or 3 relays(subject to spec) in the engine bay fuse box

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
