frozen A/C pipes

[mattmac]

Just got back from trip down the coast and when pulled into servo to fill up/ checked oil etc and noticed my A/C pipes were "frozen" covered in ice? Now i know the source of the water leak/drip in passenger foot-well when it's not even raining!

The condensate drain is probably blocked. (if the fan is working ok)

Piece of plastic whipper snipper string up the pipe from below the vehicle.

If it's a 2.2 Puma you might want to check that the "Evap coil is freezing - turn off the compressor " switch is still connected to the Evap coil

It's a TD5 but thanks anyway

Might seem like a silly question but where exactly is the drain pipe/hose located?

Passenger side, it's a piece of plastic tube that drops down through the firewall, I think near the LH chassis rail ?

Been too long since I've been under a Deefer.

Rick is correct as to the location of the drain. The other thing that has served me well, is the advice from the auto electrician, to adjust the temperature setting so that their coming from the vents is no cooler than 4˚C. I've fitted a small digital temperature gauge there to inform me.

Freezing can also occur from short of gas

If the suction line back to the compressor is frozen it won't be short of refrigerant, it'll be an iced up evap. ;)
That's if I'm reading the original post correctly.

Could be but if short of gas will start with Evap icing up and eventually working back along the suction
I'm a fridgey not a car ac one so dunno if they can with engine heat etc
But yer could also be blocked drain or fan dead

found it and pushed some cord up but didn't seem blocked so will move onto plan B- whatever that is. the other thing i should have mentioned is previous owner fitted this fancy aftermarket A/C unit in rear as well as original ones in front which may be a contributing factor.
