1994 G20 A/C only works on high

[newTechGuy10]

Hi everyone, I am a new infiniti owner and i am glad to be here. I have a problem with my climate control unit; my A/C and Heat only work on high, I tried replacing the fan blower, the climate control unit and the resister and still no use. Some one once mentioned it maybe a relay issue but I am not to familiar with cars and how to do things, can someone please help me out.If anyone ran into this issue before and got it solved please help me out.Thanks

Off to Sentra/G20 you go.

what do you mean, they have a lot of problems. b/c so far i have not had a problem, that's the only thing i ran into.....

No, he just moved your thread into the Sentra/G20 section.

First off, welcome to NICO!

Does the unit blow air at all on other settings and it's just not the right temperature, or does it only blow air on high?

[newTechGuy10]

it only blows air when i set it on #4 (the highest) and the air that comes out is cold if it the A/c and warm if its the heat, I thought it might be a control unit issue and I tried on three different ones and the problem continued....

Everything I can find says bad switch or resistor. You've replaced both, so I'm stumped.

I'll move this to the Infiniti Online Mechanic section so one of the Techs will see it and give it a shot.

Moved from Sentra/G20. Anybody have an idea?
