Vauxhall vivaro movano heater blower motor not working. How to fix, repair

So it’s a cold winters morning your frozen to the bone, you jump into your vauxhall vivaro and turn the heaters on, it doesn’t work. In this article I will explain how to repair.

There are commonly three things that can go wrong and it true to be said with most vehicles. These are the fuse, the motor, and or the heater resister. These should be checked in this order. Not only to keep costs down but is a good methodical way to solve the problem.

A little contradictory but before you do anything just check if the motor works on any speeds at all. If it does, particularly the fastest speed. It safe to say the fuse and motor are working fine, and would probably mean that heater resister if faulty.

If this doesn’t do anything you should grab the owners manual and locate the fuse. This can be checked visually by removing and looking at the fuse element or the use of a power probe and checking a power at both sides of the element.

If the heater still doesn’t work, remove the motor and wire it to a charged battery. If it functions you will conclude this isn’t the fault. If it is just replace the motor.

At this stage it’s worth checking the wiring for burning, scorch marks at the multi plugs. At this stage I would conlude if nothing else is found I would replace the resister.

Six thing to avoid as a new Reef Keeper

So what should you avoid when keeping a reef aquarium when new to this fascinating hobby? Lack of knowledge. This is very important, you should learn as much as possible before even thinking about buying anything. Books are expensive, but there are many other Articles and Informative Forums on-line packed with information and help. Hard corals. These should be avoided until a full understanding of water chemistry and a confidence in maintaining these levels are achieved. These corals require more intense lighting requirements and feeding. Compatibility also creates issues too. As above really, learn about water chemistry, then research your coral selection carefully. Expensive unnecessary equipment. As a newbie to Reef Keeping it is totally unnecessary to purchase Computers, Reactors, Top up devices, and any other fancy items that may arise. I say this because as a new Reef Keeper you need to understand and manage a Reef Aquarium. Having fancy computers and reactors will create load...
