Hi all,

I have a bit of an issue, where water is leaking into the passenger footwell (R/H drive vehicle) after prolonged use of the A/C. It seems quite obvious that is water from the evaporator. I've been underneath the car to try and locate the drain pipe so i can unblock it (this is quite easy to locate on most vehicles. I have even had the mechanic have a look at it, but we cannot seem to locate it on my car (other iO have it) so it seems the pipe has fallen off. The evaporator box is in the center console, and there "seems" (can't quite be sure) that it exits through the firewall, above the transmission, therefore hard off access to unblock. The mechanic has suggested that we take the dashboard out to access the evaporator from inside the car, and unblock the hole that way.

I'm a bit reluctant to remove the dashboard, unless absolutely necessary, as it may damage it in the process.

 

Any suggestion? Can't find any diagrams of the drain pipe in the workshop manual.

 

Cheers,

drain hole

It is a small rubber hose, exits firewall horizontal then turns sharp to face down. It's only about 15mm long.

It is on the rh side above the bellhousing. Look up above clutch slave cylinder and then move towards top of bellhousing. A length of stiff wire will unblock.

Will post a pic

ac drain

Note: the two black hoses partially obscuring the drain are NOT STANDARD - these are high-level breathers for the gearbox and transfer, you should have a clear view.
Also this is a RHD car with the clutch on the RH side - yours may be different.

Thanks for the photos,

Thanks for the photos, finally located mine. Not very easy place to access though, i've tried to get to it with wires, but seems i need smaller hands :)

For now mine seems to have unblocked itself

AC drain hole plugged

Dear Pajero Io owners,

 

I have the same problem and try to solve it but I do not manage to find this drain hole, even with your pictures. My Pajero IO is GDI model 1999.

Which side is it ? How do you acces it ? From top or bottom ?

 

Thanks

François

ac drain

it is in the middle, above the gearbox. just behind the firewall.

in RHD cars you can access it via the RH side - as the exhaust blocks access on the LHS

Again, I tried to find the

Again, I tried to find the drain but it was not possible. I went under the car (not a lot of space !), above without success. Do you acces it from under the car ? Do I need to elevate the car ? It woulf be easyer if I can access it from above.

Regards,

François

ac drain

the AC drain is on the LH side of the car but is hidden by exhaust
you can see it up from under the car RH side.

it is difficult to see but you can feel it.

try lying under the car next to the clutch lever on the outside of the gearbox,
now look upwards to the floor where it curves from horizontal to vertical into the engine bay - then pan over to look up over the top of the gearbox towards the LH side of the car.
