Toolong Posted March 15, 2022 Share Posted March 15, 2022 Got an old DMax Hi-Lander. Bought it new about 12 years ago. For first 6 years or so, the air-con (ac) was fine. Then started to repeatedly have trouble. Local Isuzu dealer pumped more gas into the system and checked this & that, including replacing some kind of (costly) component on the fan belt system. Seemed fixed (ie, cooler) but again & again it never really stayed cool and I've spent multiple 1000's of baht over the years having it seen to, including a new compressor and god knows what. Isuzu never sorted it out satisfactorily (including forgetting to put the filter back in the unit beneath the passenger seat!) and after the warrenty expired it was various small businesses locally. Without long-term, permanently- fixed success. Getting to the point of this: now once again failing to properly blow cool air. I know it's the hot season but that's just coincidence and that's not the issue. Something is wrong again and I'm at the end of my bl***y tether over this! I will seek out a new place locally tomorrow.....but I wondered if anyone out there might be able to offer advice about what it might be.....and what I should specifically expect them to check. Also kind of hoping someone may have experienced the same (baffling) situation and point me more precisely in the right direction. Sorry this is a rambling mess, I know, but any help would be appreciated. 1 Link to comment Share on other sites More sharing options...
Kwasaki Posted March 15, 2022 Share Posted March 15, 2022 (edited) Try a different Izusu dealer by posting where you live so others here can recommend one. We have a car electrical shop that sorts air-cons maybe there one where you live. Try a Cockpit or BQuik and if they cannot help they usually know someone who can.

To be honest, Kwasaki, I became a bit disillusioned with Isuzu re the air-con. Engine-wise, yes, know their stuff, but their air-con team (Pakchong btw) not so expert. I could indeed try the local Cockpit or Bquik. Basically.....I need to find 'The Go-to Guy'! The fella who really knows his business! There's always one! ???????? 1 Link to comment Share on other sites More sharing options...

ToyotaVigoThailand Posted March 15, 2022 Share Posted March 15, 2022 The only part to change is the evaporator coil behind your dashboard and you haven't even checked this... ???? Did they put color in your system to check where it is leaking ? Did they put a sniffer in the ventilation holes on your dashbord to check if coil was leaking ? Only 2 smart way to check if an aircon is leaking and you haven't been able to get it checked properly.... 1 Link to comment Share on other sites More sharing options...

Good to know this. Will be very useful to have this info when I go to the shop! Thanks a lot!???????? Link to comment Share on other sites More sharing options...

Well - right & wrong....I had a shop in mind had he been in my area that could assist..... I'm retired auto service industry - Lexus.... I would suspect a dye test had been performed + a vacuum pull down, as well as a sniffer test in the dash area..... It's typically going to be a small leak somewhere = it's locating it to make the repair....Every step is going to have to be repeated.... Hopefully, someone in his area has a decent shop in mind.....

I'll go into the local town tomorrow and ask at 5 different shops connected with the motor trade - but not air-con repair. If I get 2 or more of the more experienced-looking guys tell the name of one shop in particular......that's my starting point! ????

Interesting comment, pgrahmm. Dye test, vacuum pull down & sniffer test in the dash area. I think ToyotaVigoThailand mentioned these too, so I'll be looking out to see if they include those. Thanks a lot. (Lexus, eh? Wouldn't mind one of those.????) Link to comment Share on other sites More sharing options...
