ok so my ac only.blows real cold.when im at a stop them when driving it warms up i know i need to replace the ac fan relay but i don't see that being the problem since kt does opposite of what the fan problem would cause it to do any help please

 

Anybody please

 

i don't know if this will help much,but here go'es.there are a series of blend doors that operate defrost,floor and dash outlets.on most of the cars i've worked on they are vacuum controled,if that is the case you have a vacuum problem.ether a hose leak or a bad blend door.however this car could have electricly controlled blend doors,in which case i was of little help.good luck...steve.

 

How would i test to see of i have a vacuum leak
