SOURCE: Faulty Fan Heater - The main vents are just blowing out cold air.

all cars have a recycled air weather its called max or just recycle its doing the same thing. So if your getting cold air in one spot and hot in another it means your vents are not blocking where they are suposed to. It could be just a simple fix, by getting into the dash where your vent controls are and looking at the flap that tells air where it can and cant go. if its stuck then it needs to be cleaned and oiled. If the cable is corrodend clean it and oil it so it can move freely, or just reconnecting it may be the fix. it sounds like you are going to have to be adventurous, and play with the mechanics of your vents. Typicaly theres really nothing tough there to work on, just REMEMBER WHEERE ALL THE SCROOS AND CLIPS GO. I have forgotten where a few went in the past and had to listen to sqeaking noises till I took it apart again. There are vent seals wich are no more than the weather stripping you buy at the hardware store the 1/8 inch thick tape. You may need to thin it down with a razor, usually not. but it works great for fixing the seals in car heaters, because its the same thng just a different color. Which no one will ever see.

Behind the dash are tubes that carry the hot air to the different vents. When you select dash output, the buttons send an electric signal to motors to open flaps in these tubes. The buttons are lit, so they have sent the signal, it hasnt reached the motors or the motors are not turning the flaps, so the air does not get routed to the dash. That is what is wrong

I have a 1999 Cadillac Eldorado ETC. When I turn the heater on and bring it out the bi-level vents....The driver side blows heat and the passenger side blows ice cold....even with the air cond. turned...


the temperature door inside (there is two one for each side of car) is possibly broken if you turn the blower on low turn the temp on the passenger side from full hot to full cold or vise versa and listen closely for a clicking or snapping sound if this is heard you have a broken door in side then the dash has to come out the air conditioning has to be discharged of refrigerant which has to be done by a facility with a license. if no noise is heard it could be a control head or a motor but the most likely cause is a broken door.

I am not getting any type of heat in my 92 Eldorado. What could be the problem? There is air comin through the vents, but its cold.


If the heater control valve is not opening, no hot coolant will circulate through the heater. It may be controlled by vacuum or cable from heat/air control. This valve is a gate type like gas or water valve in your home, usually located on engine firewall. Turn it manually to see if the air gets warm in vents. IT will have 2 hoses hooked to it, an in and out from engine block or head or even intake manifold.

Sounds like the blend door actuator which diverts air from defrost,to bi-level,vent etc. It's vacuum driven and when it fails, it's usually an indication of a vacuum leak. To trace the leak, start the car, turn the AC on high and starting at the firewall in front of the passenger's side, trace the vacuum lines backward until a leak is detected. If no leak is detected, it's very likely that the blend door actuator is faulty and needs either repair or replacement. Best of luck.
