l get cool air on drivers side but hot air on both middle and passenger side.
Need help!

the best anser would most likely go to a saab or mecanic.

only reason is the air system can get complicatied if you try and fix it yourself. The problem sounds quite complicated as two blow hot and the others blow cold--

saab l would recomed but they charge HUGE pricess for small things--best of going to a mecahnic who is independant.

good luck and remember, unless you know what you are doing, dont do it, as you may worsen the problem.

Please make sure that all vents r open specially the rear ones & nothing is blocking the vents under the front driver & passenger seats. The SAAB A/C system is designed to work with all vents open & if anyone is blocked it will start to give hot air. In addition, if the problem still persists then u may have a problem in the climate housing with broken/stuck arms or flaps. This will require a qualified tech to handle. Is it the 9-3 sports sedan or the 5 door version which was continued till mid 1998.?
