Hvac always cold
Hello, So there was a post for the HVAC always Hot and mines for HVAC always cold.. Would this be bc of the same motor issue?
Im only getting Hot Air at the highest setting of 85.. As soon as I drop to 84 or lower it's cold.. No smooth transition from Hot to warm to finally cold..

Test process to figure out which part has failed is in this section: http://boredmder.com/FSMs/Nissan/Maxima/1998/HA.pdf
Probably the same part as the always HOT thread.

I'm not so sure it is the air mix motor because you can get heat at the high setting. I think that it may be one of the temperature sensors that the controls use. Run the self diagnostic on the hvac system. Starts on page 70 in the link KP11520 gave you. My guess is that you will get a 22 error.
