AboutDavid Scott Expertise Questions regarding the advisability of different kinds of modifications to Samurai/Sidekick/Tracker or various kinds of off-road usage. I will not attempt to do more than provide links for questions about other Suzukis such as Vitara, Grand Vitara, etc. I may or may not give generalized advice for newer models, but have no experience regarding newer models, and will not attempt to give more than the most generalized answers for questions regarding vehicles later than '93 manufacture. I will however, if possible, provide a link that will help you contact a professional in your region.

ANSWER: The A/C will cause a loss of power to be noticed. The power to run the A/C has to come from somewhere. As to the A/C not working well, that's a function of how much refrigerant the system contains.

QUESTION: thanks for your support,,
sir i just want to know that the low performance of a.c. is due to the back compression (or decrement in the power of engine) or it is the problem related with the air conditioning only
thanks and regards

Answer If the motor runs well enough to pull the vehicle, and run the air conditioner at the same time, then the motor is not the problem. Usually, air conditioner performance problems are within the air conditioner itself. Most of the time the problem is that the refrigerant charge is low.
