Had the same problem. Did exactly what you advised. Worked perfect thanks for the helpful advice. Saved me loads of cash.

Just want to stop by and say Thank You for making this video. I followed what you did and it fixed my blinking 4wd light.

Very much appreciate this video. There are so few videos of this model of Vitara.

You don't even need to put it on a gauge to test this issue.

When my 4x4 light began to flicker I first replaced the hoses, but then like you, I found my problem was within the air-activated 4x4 actuator itself.

That worked perfectly! Thank you so much for the great video. My 4x4 light was flashing before and now is staying on !

Thank you so much. I have this same issue on my 03 Chevy tracker but my mechanic, who checked all vaccum lines, couldnt find any issues. The 4 wheel drive still engages for me, just that the light flashes continuously. He thought maybe there is something in the circuitry which he couldnt identify. But like I said the 4 wheel drive does engage. Next time I'm there ill show him your video and see if he can give it another whirl.

Thanks works like a charm now! No more flashing 4x4 light! I also decided to mount it up higher behind the grill to keep it out of water and potentially getting damaged when off-roading. 👍

Hi mate I from Ecuador and I was having trouble with my 4wd ligth, thanks to this video I was able to fix it my self and it's working properly now, thank you and good luck! 🙌

Worked for me. Just to add the pump is mounted on a metal bracket. 2 bolts to remove the bracket the 3 screws to remove pump from the bracket. If you don't have a vacuum gauge just put your finger over the nozzles where the pipes fit and see if the pump 'cycles'

Thanks for this guide. My 2003 appears to have had this exact same issue. Fixed- hopefully- using this guide. Cheers 🍻

Very helpful video. Fixed the same issue on my GV. Thank you!

Same issue on my '03 Chev Tracker. After fixing the o-ring issue I reinstalled the valve to the top of the radiator on the passenger side. Zip tties to hold it in place. Doing this keeps the valveup high and out of the salted road slop in the winter which leads to corrosion.

Exelente aporte !!! Con tu experiencia reparando pude solucionar la avería de mi GN. Muchisimas gracias por compartir!!

Thank you very much for this. Worked for me too! I didn't have any grease on hand, doesn't seem to matter. I replaced the o ring with one from a packet of mixed o rings from Bunnings.

This helped with the pump on my grand vitara 2005, thank you.

It definately works! Can't thank you enough mate!

many thanks for sharing this. I fixed my car using your video. Best regards from Brazil!

Merci pour la vidéo, après avoir débranché les durites d'air sur cette petite pompe, j'ai bien vu qu'elle fonctionnait toujours par intermittence, alors que normalement si vous bouchez le tuyau de sortie d'air , la pompe devrait s'arrêter...j'ai nettoyé comme sur la vidéo et changer les deux joints toriques. Le voyant 4wd arrête de clignoter, et la pompe s'arrête de pomper pour rien. Parfait. Grand vitara de 2003.

Mate you’re a legend thanks so much for this vid 👍
