A/C Problem

[c.herrm]

I've been having A/C problems for months and i dont really know whats going on with it.

My A/C works great whenever i am stopped at a red light but as soon as i start driving again it gets back to warm air.

Does anybody have a clue what it could be.

Another thing i was wondering is does my 98 Ford Explorer Eddie Bauer edition have a cabin filter? If so where could i find it?

as far as the cabin filter they were not used untill 02 andup i believe?? as far as cold at idle you have (a) low freon (b) dirty condensor but I would bet it is just low freon

i recently added new freon and that didnt do anything at all. how do i find the condensor?

 

[97ford50x]

the condensor is in front of the radiator right behind the grill you might also have over filled the system how much did you put in?? and did you use a gauge

i had a professional put the freon in my truck.

how exactly do you clean the condenser?

 

[97ford50x]

water hose or compressed air how long ago did they charge it??

 

[c.herrm]

about a month ago....would i have to take the condenser out to clean it or can i just spray water on it through the grill

 

[97ford50x]

just hose itout through the grill but i would call the shop that did the work and tell them it is not working properly and see what they tell you since it has only been a month they should be willing to help you if you would not be so far away i would tell you to run it by the shop i work at and i would look at it for you

What are the presures?

Sounds like a vacuum leak to me.

There may only be enough vacuum to hold the blend door in the correct position when the engine is idling.
