Could be the hvac fuse probably located under the hood

Testimonial: "The replacement of the 10 amp A/C fuse did correct the original propblem. Now there is a loud clicking sound from inner rear panel?"

  • Freddy Apr 13, 2011

    That clicking noise is an actuator that is trying to move, but is binding. You will need to remove the side panel to access this area and determine the cause.

Cold air comes out front vents in 1999 windstar


Usually a sign of a faulty blend door under the dash. The blend doors direct air thru the heater core and the vent outlets. One blend door is directly behind the radio.

It blows out hot air even when the air in the front is cold


Hard to read your question, do you mean it blows cold air out of the front vents and hot air out of the rear passenger vents?

If the air coming out of the front is just cool and not cold, and the rear vents are warm, you have low freon and need to have it serviced.

How can I determine if my compressor is out on my


If you still get cold air out of the rear vents but the front only blows hot air you may have a bad temp door actuator in the dash, it may be stuck on hot and not able to move to cold air. However if you are low on freon with a truck that has front and rear ac then there will be a temp diff between the two. If it is hot air out the front like the heat is on then you have that actuator problem but if it is cool air about the same as the outside air temp then you may be low on freon.

Fully warmed up; blowing hot and cold; Suzuki XL-7


Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.
