Hvac problem

[KWT2000]

hey all, well got my A/C fixed today and it is working good..

but now there is another problem..

at idel the air comes out the vents like it is suppose to but under moderated to hard acceleration it goes up to the defrost then when you let out of it, it slowly... returns to the vents...

also when i turn the key on after sitting it is always blowing out the defrost no matter what setting until it idels for a bit


any ideas on where to look??

TIA

Check vacuum that comes from the intake and goes to the ac controls, make sure you are pulling enough vacuum from the intake, use a vacuum guage, also make sure the vacuum tree at the controls are tight and are not leaking

also look at the vacuume line that goes from the PVC line to the intake I just did one yesterday on a friends truck 03 120000 miles hole in it

that is just plain GAY!!!! I can see the plate issue but no mud flaps... don't follow so close... glad it isn't a prob in NY.... but the plate issue is the same...

i agree 100% and they only have to be half down the tire... with big tires they are still going to throw stuff

love your sig...lol... might need to get one for lane24... keep the lifted red EB club together...

 

[KWT2000]

absolutly...

 

[tallsville]

give lane yellow. then a couple more lifted red expys and you'll have the whole flag. btw kwt that sucks they pulled you over for that. usually they only add that to tix anfter pulling over for something else like speeding

i didn't get a ticket just a warning, but i rerely get tickets as i have prepaid legal and it is stated on my licens..

but it is stupid but i came home and look over the lift laws for my state and sure enough fender flares and mud flaps are required for all vehicles and they have to reach the axel center line
