Where is the heater blower resistor located?
It’s located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.
Where are the relays on Renault Trafic?
Hi, there are no relays in the window winding system of the Renault Trafic the system is powered from two fuses, fuse 18 which is marked up with a stereo icon ( so if your stereo works this fuse is good) and fuse 21 marked up as a window going up and down, this powers the switch control ( the plastic piece with all the …
What does a resistor do in a heater?
They are designed as a special type of power resistor to provide a reliable and controllable source of heat. A heater resistor can produce convective heat, meaning it heats up the surrounding air, or radiant heat, meaning it heats other objects directly through a phenomenon called infrared radiation.
Where is the fuse box on a Renault Trafic van?
The fuse box is located behind the storage compartment below and to the left of the steering wheel.
How do I know if my heater resistor is bad?
Symptoms of a Bad or Failing Heater Blower Motor Resistor
- Blower motor stuck on one speed. A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting.
- Blower motor does not work on certain settings.
- No air from the vehicle’s vents.
What happens when a resistor fails?
When a resistor breaks down, current typically flows through the burnt resistor without any resistance and thereby passes unchecked. Other components in the circuit may become damaged from the excess current flowing through.
Where is the fuse box on a Vivaro?
The fuse box is located on the left-hand side of the instrument panel, below the cupholder. Remove the ashtray from the lefthand cup holder and pull open the fuse box cover. Do not store any objects behind the cover.
Why is my Renault Trafic heater resistor not working?
The other 3 settings resulted in the motor not working. When this happens the resistor is usually the problem. In some cases the motor will go onto full speed regardless of what it is set to.
Can a Trafic van have a heater problem?
Have a Trafic van that has now a heater blower problem First i lost two of the 4 speeds of the blower, i.e nothing happened in positions 1 and 2. Recently I have lost blower action in position 3.
Why is the resistor on my Trafic not working?
When this happens the resistor is usually the problem. In some cases the motor will go onto full speed regardless of what it is set to. To access the resistor means working in the engine bay, the trafic like most modern vans features abysmal engine bay access, although its not too bad once the air filter housing is out of the way.
How much does it cost to replace a resistor in a Renault Vivaro?
Its an easy DIY fix, the new resistor unit cost £18 on eBay, genuine Renault ones are about £40. The Nissan Primastar, and Vauxhall/Opel Vivaro are identical to this van (Badge Engineered) and should they give the same problem the repair should be similar, although double check the connectors just in case they may have slight variations.
