I have a problem that I have researched for awhile and nobody seems to know whats going on.
I have a 1999 Dodge Ram 1500 4x4 5.9...when I run the A/C and have to accelerate real hard...the blower motor seems to stop. Other words, no air comes thru the vents until I let off the gas.

Any ideas? Or has anybody had this problem b4?

Thanx in advance

 

search wild vents, its just a check valve or possibly a vacuum leak. Just search wild or wacky vents and you'll find plenty of info.

Im hoping it's a vac leak and not anything major......but it would cause the blower motor to quit????

 

It's not stopping, it's just blowing out different vents. Defrost probably.

 

gotcha....each time its happened...Ive turned the blower switch to high to see if I could hear it still blowing, and I have'nt heard anything.....either way I guess Im gonna have to check it out.....whats the MOST COMMON problem (where I should look first?)

 

Your truck is trying to tell you to slow down.

 

Trace all the vac lines from the passenger side of the intake. And the cruise control line too, conveniently located under the battery box. And replace the check valves regardless. I know that thread is quite long, but it has all the info.


The 4x4 lines to the front axle also.

 

thanx a ton for the info
