AboutJohn McInnis Expertise Land Rover Discovery.
I've had most of the common mechanical failures, altenator, water leaks, wiper failure, door/hinge problems, roof rust, floor rust, loads of electrical problems. Remember, I'm not a dealer or a mechanic, just an owner like most of you.
Experience
Experience Owner of a Discovery. I've had many mishaps with our Disco but I still like this vehicle. Talk to a fellow LR owner instead of a dealership rep. I'm not in this for the money. I'm just an owner who wants to help others.
I just bought a 2003 Range Rover with 50,000 miles on it. Everything has been fine except the other day my air conditioner stopped blowing all together. However, my rear AC works fine. When I turn the AC on I can hear something turning on but no air comes out.
Please help!!
Thanks so much,
Chris
Answer Hi Chris,
sure sounds like the blower motor.
From RAVE:
Blower
The blower is installed between the air inlets and the evaporator, and consists of two open hub, centrifugal fans powered by a single electric motor. Operation of the electric motor is controlled by the ATC ECU via an output stage (voltage amplifier) installed in the outlet of the RH fan.
To produce the seven blower speeds the ATC ECU outputs a stepped control voltage between 0 and 8 V to the output stage, which regulates a battery power feed from the passenger compartment fusebox to the blower. The control voltage changes, in 1 V steps, between 2 V (blower speed 1) and 8 V (blower speed 7). If the control voltage is less than 2 V the blower is off.
