bring it on...
mei to AC ke sath chala raha gari...i did 445km in 36.58ltr petrol with AC full time.
Money differs from an automobile or mistress in being equally important to those who have it and those who do not.
Ok guys so here is how today I removed my Liana's fan from direct setting. First of all, this is what service manual tells about the fan control circuitary.
This basically means that the pin 18 is connected to the collector of this npn transistor (must be internally pulled up) and as soon as it is pulled to ground, the fan will turn on. So...
I took my multi-meter and went down to the garage and popped the hood open. Under the radiator fan relay box housing, I was able to find that this brown cable from C21-18 was forcefully pulled to ground. Here are some pictures.
I removed the tape from this joint and pulled off the ground wire from the brown one and that was it. My fan was no longer direct.
I then started the car and let it run for about 15 - 20 minutes at idle. Engine temperature needle steadily rose to around midway between C and H mark. But then, instead of the fan coming on, the car hesitated and engine died. Check engine light also came on while engine was hesitating, before I turned the key off. I also noticed that when I turned the AC switch on, only the condenser fan was running instead of both the fans. Seems like there is some other mis-connection that I need to find out. Will keep on investigating. Any suggestions from experts are welcome
This looks interesting as well. My ECT sensor connector and the ect sensor connecting pins are a bit dirty. I'll wipe them clean with a carb cleaner and see how it goes the next time I let it warm up. (fingers crossed)
As soon as I watched the above video, I was sure that I had the same problem because the car was idling but it was intermittently idling high and there were no codes on the odb2 scanner tool. Just a while ago I took out the ECT sensor and its connection pins were REALLY covered with dirt. It must have been making a highly unstable connection due to engine vibrations as engine was started. I sprayed the connection pins liberally with NASA carb cleaner that I had in stock at home and it was all nice and clean. Did the same with the connector along with gently scrubbing with a sewing needle. Then put it back on and started the car. It seemed MUCH more stable this time. Don't have time right now to let it warm up completely as I have to rush for office but I hope it will solve the issue. If it doesn't, i'll be replacing the ECT sensor because i'm sure the previous owner didn't change it even once during the 10 years of car's life. And if that doesn't fix it, i'll try a professional scanner since right now I'm only looking at it through a portable wifi scanner that connects with my phone.
After reading your post, I thoroughly analyzed my car's cooling fans. When I switch on AC, only one fan runs, while the other fan only runs when coolant gets hot. May be there exists some problem with the wiring. I need to trace it first.
Here are a few pics of my Liana eminent bought in Sept 2009 from Suzuki Islamabad Motors
Alhumdullilah by the grace of Allah have tried to keep the car neat and clean
Currently it has done 118,320 K.M. Here are a few pics which i took today
