Cars Q&A

Continuing my question below: I have another problem. If the ac is on for sometime, and then i switch off the ac with the blower on, i get a dusty humid smell out of the vents. I tried applying the neutralizer, but the smell persists and comes the neutralizer smell mixed. i think, there is dust/dirt accumulation somewhere. Where can i get it cleaned? Can i clean it myself? My dealer doesn't have time to do it. hi, i have a Ford Ikon 1.6 2003 model. Good running condition and well maintained. I feel that, the pick up in 1st gear and 2nd gear has reduced compared to earlier days. Also, while ac is on, the ac makes a noise which can be heard from outside, not from inside. is it normal? Is the ac overloading the engine, which is responsible for slower pickup? What average should i get on city with ac on? If i fit LPG kit, will it be beneficial for me? please advise..
