Re: Renault Scenic II - Access the resistor pack in 5 mins.

I received in 2008 some criticism from some of you for not being willing to publish the full design of my resistor substitute using 10 of components. This consists of 3 resistors on a heatsink that mounts behind (as you look at it) the easy to get at fascia by the handbrake control. It is wired into the fan switch so there is no need to access the difficult to get at blower area.

aahbarnes publication of his simple way to get to this area rather negated the value of my solution as it is now easier to reach the blower. But not that easy, especially if you have not got slim arms, and you still need to buy a new resistor pack and replacement loom from Renault costing >>50.

I was unwilling partly because I was concerned it might catch fire and I did not want to get blamed by others copying the design. My unwillingness has been partly justified as it has failed twice in 3 years, but nowhere near catching fire.

One resistor burnt out as the heatsink proved not big enough to keep it cool. I added a small cooling fan to the heatsink but would choose a bigger heatsink instead if starting from scratch. Then it failed because it was still relying on the blower current flowing though the loom via 2 of the old resistor pack connections. These eventually burnt out. I had to remove the connector using aahbarnes method and short 2 wires of the loom to take the current straight from my resistors to the blower.

So the 10 solution still works but needed some design changes and a lot of man-hours.

Re: Renault Scenic II - Access the resistor pack in 5 mins.

Hi all i have just repaired my heater resister part no:7313N1020 on my 2008 model as I had no heater speed at all . Followed the instructions and pictures on recent thread to find out that I have the green large and small connections. And also held in with only one screw, which is an absolute pain to get too. Using the wifes make-up mirror to assist me. After taking a few bits of skin off my wrists I managed to get the resistor pack out. Only to find out that the connections, i.e large and small green ones were hard to un clip, certainly not as easy than 1,2, and 3. Managed to get them out taking a little more skin off the wrist, and noticed that were the black wires go into the resistor pack was slightly melted. And the soldering on the back of the circuit board was discoloured.So i re-soldered were the black wire goes on the big block of the circuit board. So this is were it gets tricky. I noticed on the small block were the black wire goes on to the terminal on the resistor pack had melted a lot more, and looked like it was touching the red wire terminal. So I un-soldered the black wire terminal pulled it out of the circuit board and block altogether. Cleaned up the terminal, and were it had melted in the green block used a 2mm drill bit to clean out the green block were the terminal goes. As it was dis-formed. I got the terminal and a little tiny bit of wiring sleeve, sandwiched them together and gentle put them back into the green block. Hopefully seperating the red and black terminals apart. Re-solded the terminal back to the circuit board and re-fitted to the car. AND IT WORKS!! Saving myself a small fortune. I have noticed that some of these resistor packs are selling on ebay for around 40, they look the same but some of them have different part numbers. Hope this helps.

Question Re: Renault Scenic II - Access the resistor pack in 5 mins.

Hi all, new here and have already learned so much. I'm gonna replace resistor pack on Scenic II because like everyone else mine has gone.

Some great pics on the thread on how to access it once you get that section of the dash around the clocks out, but can anyone tell me where the screws/mountings are to get that section of dash out in the first place?? Pics would be great!!!

Re: Renault Scenic II - Access the resistor pack in 5 mins.

No screws, it just clips in place. Start with then top piece and pull it down firmly.

Re: Renault Scenic II - Access the resistor pack in 5 mins.

Great thread and thanks for all the tips!
My fan has just stopped working on speed 4 (Scenic 2004 1.9 DCi, 170k km).
I've ordered the connector+cables and will try that before changing the resistor pack.
My car is Left Hand drive.
Does anyone here know if the installation of the resistor pack in a LHD car is a mirror image of the RHD?
Or maybe it's installed the same way round as in RHD, and then I'm wasting my time trying to do the 5 minute swap?
