you have a vacume leak probbly going to the heater control There is a check valve that prevents the loss of vacuum to the heater controls. This check valve goes bad. Then, as you accelerate, the vac. in your engine drops and along with it, the vac to the heater controls drops (is less). To fix this, locate the check valve and replace it. Follow the vacuum line from your firewall (where it goes through the fire wall) back to the check valve. This check valve may be located between the engine and a vacuum reserve tank. The heater controls may be using the vacuum from the reserve tank. In any case, find the little check valve in the vacuum lines and replace it. You will see a remarkable change in the heater controls. I hope I explained this well enough. See you Later, Check your intake gasket if it is leaking at all it will cause it.
The AC on a 1998 Dodge Ram 1998 will only be blowing out the defrost vent if the air handler is not set properly. This can result from a piece of debris getting stuck or a faulty flap.
For a 2009 Ram, Yes.Try experimenting with the AC/Heat Controls. I have noticed when defrost is on there is a miss in the acceleration, but when the floor heat is on, the acceleration is okay. I am taking mine in to see what they say about this. My 2000 Dakota had a miss in the acceleration but the dealerships could never find the problem (or did not care).1973 Dodge Coronet (318 Auto); 1993 Dodge Dakota Sport (3.9 Standard); 2000 Dodge Dakota Sport (3.9 Standard); 2009 Dodge Ram (4.9 Auto)...Things have been going downhill ever since I brought the 2000 model, and am not happy with the 2009. Needless to say, this is my last Dodge.
If you have all of those symptoms, it sounds like selector on front dash is all shorting out, or your PMC module is acting up sending all different singles.
since their stupid and dumb ahhahahahah
Make sure you have vacuum coming into the cab from the engine. There may be something wrong with the switches.
All depends on the engine you have, the hemi has great acceleration.
2001 dodge ram 1500 ac and heater flow regulator switch does not work. works only on defrost. How to fix?
if its blowing, but not blowing cold its low on coolant. it takes r134a.
Turn key to on position depress the acceleration pedal slowly three times then turn car off...
change the intake and carb worked for me and the intake manifold needs to be cleaned out
There may be several reasons why the air only blows out the front vents and not on the floor or the defrost on the 2003 Dodge Ram. The fuses may be blown, or the heating coil is not working correctly.
You're out of fuel?
