Bongo Fury

Zipped into Kwik Fit today as the heat coming out of the front blower is considerably warm, even on 18c on auto.

They stuck a hose connected to a machine on the blue screwtop thingy in front of the rad, read it as being the same as a B2500 (?) & let it run its course for half an hour.

At the end of the cycle it read Leak Found - Needs Repair.


The lad who had proudly told me that he'd been on a 2 day course on this particular machine recently had no idea what to do next.

Any of you lot any ideas???

wheres it leaking
tbh i wouldnt trust a kwik fit operative to check the tyre pressure.

When I bought mine I was told the aircon needed recharging but I decided to get an independent aircon guy to check it. Turned out it had a fractured pipe (near the charging point inI wd front of the radiator. Luckily the vendor was able to call in a favour with mate and one was made up and fitted aircon regassed, within 24hrs otherwise I might have pulled out of the deal (the other half would not have entertained a Bongo without aircon!). Might be worth contacting an independent aircon man to ask if they can get pipes made up and/or identify leak location?

Don't know about Kwik-Fit, but garages normally have an air-con gas detector to find leaks - it was part of the gassing machine where I worked

You might be able to find the leak yourself with an aircon dye?

I was always under the impression that the Air Con machines..... purged the system and then refilled it including leak sealant/oil/gas to the measured amounts........
Another alternative...... and they do work, I can vouch for it...... the EZ-Chill aerosol jobs from Halfruads and the like..... they too contain leak sealer/oil/gas...... I have had the experience to use one on a vehicle...not mine though..and the same symptoms as your describing Chris.....

Noticed coming home this evening that when I flick the A/C on I'm not getting that ghost foot effect, popping the revs up when the air con kicks in.

Brilliant I thought, just a fuse!! Had a look at the fuse factsheet, found the right one , prised it out & was chuffed to find nasty black stuff on the spade terminals.

Unfortunately the fuse itself is intact.

What next?

Is there a relay I need to look at?

Have a look at the 2 little vacuum actuators above the fuel pump under the drivers seat (mitsubishi badge on em probably) one controls cold start fast idle & one is the a/c fast idle, could be the actuator is duff, connections need cleaning or the vacuum pipe has broken. Most bongos I've looked at they don't work.

Ok. Worth a look.

Possibly unrelated but for about the same amount of time that the A/C hasn't worked the fast idle from cold has been fluctuating up to about 1200rpm.

Could be a clue . . . .

Most aircon gas has a dye in it, if there's a leak your man shines a UV light around the system and says, "Here's your leak Mate".

This is rather more help than, "Computer says, 'Leak' ".

Problem there though Bob is if the pump ain't pumping, nowt comes out . . . .

My proper refill after blanking off the rear cost £40 & they had a proper sniffer jobby to check for leaks (used it to check my home made blanks)

Swap the white connector over with the other one & switch on the aircon.. If the revs come up it's the vacuum actuator?
That's how i sussed it!

CAN ANYONE HEAR ME?

THE PUMP AIN'T WORKING


I may be a small soft toy & more than happy to be corrected but surley if the system isn't pumping, it isn't going to leak.

1st job is to get it pumping then I may have some chance of progressing . . . . .


Is there a relay involved here?

What i was saying was get someone proper with a sniffer to find the leak - read this one? - http://www.igmaynard.co.uk/bongo/forum/ ... it=air+con
