There will be a connector providing power to the blower motor. Have you checked if full voltage is reaching the motor? There could be some carbon build up in the fan speed switch that is not allowing full voltage and current from reaching the blower motor hence at full speed the motor is not turning at its proper speed. For example if the battery voltage is 14V while car is running, then at full blower setting, is the blower motor also receiving about 14V?

No brother. Mujhe bhi uss connector pr shak hai i think usse desi mechanics relay hi kethy hai. Mei usse pehly check krwaon ga agar throw theek ho gae to sahi warna blower motor mei hi masla hai. Lkn still main issue cooling ka hai. Kal aik 660cc Pakistani alto dekhi uske window ke sheeshy full fogi type hway thay andar inti shandar cooling thi. 🥲

Ok brother. From now i will search on internet as well as on offline market. I will gather suggestions from local ustadzzz too. Then i will make a decision. The main probelm all the car which i have tested so far are al ready 10-15 years old. Like alto and cultus 1000cc. And as far as cooling is concerned for now (after 10-15year) if we place our hand near ac vents the air comes quite good (itscool) but not enough to cool the entire cabin. And also not enough to travel in 40degree temperature. But if we take a look at bigger cc cars no matter even they are 20-25 years old or even 660cc 4-5 years old car their ac are just amazing. Even its enough on speed 2. So first i will gather some suggestions. 2nd if all fails then i have to find a latest compressor which have more cooling and also puts lesser load on engine. Kunke alto aagy hi petrol pr bhaari hai

I have 35 years of experience in the industry as a mechanical engineer. One thing I have learned is to use the right tool for the job. Putting the hand in front of the vent is subjective. The right took is to use a ac vent thermometer. It takes away guesswork.

I restored a 1985 VW van. This car had R12 refrigerant which has become illegal since 1997. The van ac system had to be converted to R134a. Much work was done and in the picture below you can see me checking the ac temperature using a digital thermometer.

Click on the picture to see full image in this picture temp is 18 degrees which on the test drive dropped to 8 degrees.

If you want to do the work right, read up and do research, educate yourself as you have decided to do, use the right tools and then proceed to do the work. In this way money is not wasted on stuff that is not needed.

Thanku for your response. By seeing the pictures u attached no doubt u done a pretty good work . But i just mentioned that hand thing for a example. I already know thermometer thing even i have always test my car ac in dubai using this method before service. Because the charges are here too high.as compared to Pakistan. By the way theres a reason why i am.posting this thread so that i got some suggestions from experience members which have some kind of experience in replacing or changing compressor or etc for better performance and minimum load. But its ok i will do now on my own. Because the suggestion u gave me are good but the problem is still there. Even my compressor evaporator gass are all good.
