Heater resistor

[Norton]

Looking for a heater resistor for my ‘91 90 if anyone has any leads? Called around it appears to be no longer produced.

RN suggested replacing just the resistor. Anyone tried this and what resistor is the closet match?

You can use any heater resistor. It just needs to fit the hole. Delco ones use bare wire so make sure that they don't touch anything when mounted.

Any resister will generate heat.
The more the voltage drop, the greater the amount of heat.
You could buy one of the old style ballast resistors to see if it doesn't burn out with continued use.
Just google ballast resistor and then click images and pick the one you want to try.

Thx we figured that. Hoping someone had done it already to cut down on the trial and error ;-)

I just bypass that resistor because the fan is too slow already and the resistor makes it run at half speed, so it goes from too slow to painfully are you kidding slow.

One of the best mods I have done to mine. Finger tip control and variable speed just like a normal car

Nice.
It looks like it controls the cables and runs a rheostat at the same time.

I've also thought about replacing mine but frankly the high speed is all I ever use it on!

That being said for if I ever did have to replace it I would just buy a $15 mustang heater resistor coil pack available at any auto parts store and solder that in to where the existing resistor was.

It actually replaces the resistor and fan control switch. It is nit linked to the cable ta all. you just open it and leave it Tucked behind the gauges. You can install a choke cable pull and hook it up to that cable if you like. I did not. Never had any issues on or off road including submerging whole bonnet from time to time.

Here is my install detailed a few years ago.

There isn't a picture of it before installation on the web site.
I believe the picture shows a LHD install.
So the factory OEM control works the fan speed on one side and the other side has 2 controls that work the flaps from off, to windscreen, to floor and then how much heat if any gets blown in.
This new replacement switch only replaces the control on the right for fan speed.
To use this replacement switch in the link, you would have to remove the OEM stock resistor that reduces fan speed in the OEM factory scenario (that this thread is asking about).
To get "like a normal car", you would have to install a more powerful fan motor that would have a much higher air flow.
If you happen to install this new fan switch and stay with the stock OEM fan motor, the air flow will be lethargic just like it is now.

No. It replaces the fan speed switch. It can be installed on either side for RHD or LHD. It uses PWM to control the speed. If you don't mind a normal round knob, you can pick up a PWM module for $10 to do the same thing.

Correct and good to know, thanks for the post!

So if I understand, if I just remove the resistor altogether, I get one fan speed, aka Land Rover hi speed. Right?

 

[Red90]

There is no need to remove the resistor if you are just using high speed. It has nothing to do with the high speed.

Every "older" car has a heater resistor. If you want to replace it, just get one from another car that is about the same size and make it fit.

Copy. Now I understand

 

[RDavisinVA]

No you don't use the resistor with a rheostat (the switch in post 6) as the rheostat is the resistor.

I have the same issue, was looking at the dutch part as well, subscribing to this thread.
