I recently purchased a 1999 Range Rover. Shortly after, I noticed that there was water leaking on my foot by the brake pedal, whenever I had the AC on. Now, the AC does not work at all. I am wondering if anyone has an idea as to what could be the problem/how to resolve it. Thanks!

 

The water leaking is probably from the a/c drains being plugged up. However, are you sure it is water and not coolant? Water from the a/c is usually leaked from the passenger side when the drains get clogged. BTW, what country are you in, and is your rover a gems or bosch model?

 

Scott, SAME DEAL with my P38 on the drivers side and ALWAYS wet, PLUS the thing over heats at the drop of a hat EVEN with a new Radiator, thermostat and water pump all installed by the dealer.
Is that water from the HEATER CORE?
Also on Subject, when the P38 starts to get to hot the A/C quits and blows HOT.

 

Condenser fan working?

 

If the moisture on the floor is coolant, then yes it is definitely the heather core. If the o-rings are bad, coolant will seep out. However, it overheats so the core might be old and clogged up too. Here is the replacement procedure, I haven't done this myself, but it looks pretty straight forward: Heater Core Replacement (Range Rover 4.0/4.6/P48)

As for the a/c going out, it could be for a number of reasons. My condenser fans almost never come on, which is pretty typical on P38s. The cause of your the issue is probably sensor related. You can override the automatic system by moving the temp down to "LO". If that does not turn it back on, then you now know its not the interior temp sensor. It could also be possible that it is turning off the a/c to protect your engine from overheating. Running the a/c compressor with an overheating prone P38 is just asking for it.

 

Have you checked your hoses for gunk? Its odd that your overheating with a new radiator, water pump, and thermostat. What thermostat are you using? I use a 180 in mine. The dealer recommended that I use a195, well with a 195 and a new radiator and fan clutch I overheated, went above 9 o'clock and I just about flipped out. With a 180 even on the hottest days I am just fine.
