Question about Land Rover Range Rover

Open Question

2003 Range Rover 4.4HSE A/C not working when a/c button is pressed. It just blows hot air. Checked fuses, freon, control settings etc. All seem ok. Even tested the compressor & blower fan (by bypassing the relay) and all perfect. It just wouldn't blow cold air! Any suggestions please? Thanks

You need to have your mechanic flush and refill your system because the do it yourself kits do not vaccuum the system to a negative pressure or add the proper oil to the lines.

SOURCE: A/C blows cold on floor and windshield, not thru dash vents

This recently happened to my mustang and I found a broken vacuum line that connected to a "vaccum block". I'm not sure of the name but if you follow the vacuum line from the master cylinder it will lead ya right to it!

You first should find out if this is correct behaviour, because most cars after 1982 have an electronic fan which is actuated according to the temp guage in your cooling system, so even if your ignition is off, your fan still works to cool the motor (although they are mostly japanese cars that do this).

SOURCE: range rover 2003 transfer in neutral help please

hi, this is a long shot so dont give me negative if no joy.
on the p38 they suffer from a bad electronic selector.
now, i do not have a clue what gear box or transfer you have.
any way if you look at your transfer, beside where the prop comes out, is ther like a window wiper motor with 6 wires.
if so they get stuck, rust or dirt etc.
have you checked your fuses, alos i would add. again not sure on your model.
in the fuse box there is a blank fuse, when inserted it shifts it to neutral.
the dealers wont tell you where it is.
have you put any fuses in etc, i did this 5 year ago, a p38 was jump started, leads wrong way.
i got a call as the aa did not want to help anymore. aa had a hand full of fuses out, i stuck in were contacts were. after new ecu had no drive.
you are sure its not a gearbox fault, get back to me if not sure, i can tell you how to test this.

do a pressure test. You may have lost freon to the point where it will not let the compressor come on. If you do not have any gages or access to a gage, buy one of the cans of freon that has the low pressure gage attached. Make sure you get the one that has 134A with sealer. The pressure should be about 100psi not running and go down to about 60 when it is running. IF you have a slow leak and the system is low, the compressor will not come on. If you get very low or no pressure when you hook up the can, don't waste your money, have the system checked for the leak. You must vacuum the system down to 30 inches of vacuum before refilling if it is empty, and it does not good to fill it if it is just going to come back out.

Hope this helps
Rich

Hi my rangerover heater is blowing out cold, everything else is working just the heater isnt...


Most likely your thermostat has failed and is stuck open. Engine coolant goes through the heater core and is used to heat the air that is blown into the cabin. If the thermostat fails, the coolant doesn't stay inside the engine long enough to absorb enough heat to make the climate control air blow hot. Change your thermostat (flush the coolant and have it replaced while you do this), and you should be back in business.

2003 COROLLA S AIR CONDITIONER BLOWS HOT AIR.5 DAYS AGO MECHANIC "CLEANED LINES AND PUT IN FREON" FOR $135.00. STILL BLOWING HOT AIR.


If it blew cold air after freon added and 5 days later blew warm, you may have a leak in the system. Also check and see if compressor comes on if not you may have an electrical issue, relay for compressor,coil on compressor, etc.......

Heater and air conditioner aren't working


first check and if the thermostat is working. take it out put it in hot water. the thermostat should open up. also put a temp gauge in the hot water so you know at what temp it opens up. start there. dont forget theres more fuses under the hood for the ac unit
