Need help in finding what to look for about my mothers car. The aircondition will not come on unless you put the fan on all the way. I have some people looking at it but it will cost a lot of money in which I do not have. My mother's car is a '93 nisson ultima.
The problem: the fan only comes on at full blast on number 4 but as soon as it is turned on the compressor kicks on at settings 1,2,3. Switch settings range from low (1) to high (4).
