Default Exact location of A/C/Heater Relay on 91RRC?

My heater has not worked since I got the car...the heater core gets hot and I can feel the heat emanating from the dash, but no blower...

The rest of the A/C system works perfectly.

99% of these are blower motors.

mine did not work. first it was the heater switch itself which controls both the heater fans and the airco fans. Once i fixed that, it still did not work, only with the switch on highest position. This appeared to be the resistor pack. Some resistor packs are within the blower unit but for my model it was positioned under the cowl. Some difficulty finding one but eventualy got a very good after market model from british atlantic. It is al working again.

is there a way to test if it is the blower motor? without tearing the dash apart?

This truck has been in the drink more than a few times. Once coming through the hood air scoop thing and through the AC vents...

I had not had the truck long enough to see if the heater worked at that point though so I dont know if that particular splash ruined something.

I've got a 97 disco parts truck that appears to have at least one blower motor in it that I might scavenge. What blower motor do I need to remove from it (i.e. which one is the heater blower motor)?

The heater blower motor is inside the black box. It is not visible until the dash comes apart. The two fans that you see under the passenger side are AC fans.

The heater blower motor is a do-able project, well written up. Even I was able to do it.

The most difficult part for me was disconnecting the two heater core hoses off the engine side of the firewall. 2nd mos difficult was splitting the heater box apart. Everything else is just small screw and small wrench work.

one thought- Replace the resistor. do it first and see if it solves the problem and if it does not, you'll want a new one in any way. When ours failed, we lost all the speeds except high. I don't know if they could fail completely and stop all fan speeds

so what writeup did you use?

PTSchram, do you have a website you sell parts through or should we do the email thing?

I'm working on a shopping cart set-up, but it's taking forever as it is a lot of work.

E-mail works fine. pt@ptschram.com

I can have one mid-late next week.

Ok, I'm probably going to take a look for that relay sometime this weekend. Is it easy to get to?

If that doesn't work, I'll be messing with the fan after I find a good walk through.

AB has this on their web site - click on instructions
Heater Blower Motor - Land Rover & Range Rover Parts

okieRover offer some good insight
OkieRover.com
Between the two, I was able to get through it. Label everything. By the time you put it back together, you will have forgotten which way to route it and connect it. Use a digital camera to take pics each step of the way as well.

So I put the green relay below the heater air conditioner relay into the heater air conditioner relay. No change in anything. I am assuming it is the heater fan now.

After seeing the size of that monstrosity and the fact that I have to take my dash completely out of the car to get to it...I'd rather punch myself in the nads. No heat for me! Thank goodness for Florida weather.
