NO problem.thanks for watching
Thanks so much for posting this. This saved me allot of troubleshooting time. I found the tube goes from the location you indicate in the video over to a vacuum port on the intake manifold on the drivers side. Mine was cracked in the middle where it was draped over the alternator. I bought a 3/8 vacuum hose and just pushed it over the original rubber connectors on the original plastic hose. Blower switches perfectly now. Thanks so much:)
That skinny hose is on the driver side valve cover, hooks up to the valve it runs across the motor and hook up to a (T) shape air splitter one runs to the ac canister and the other runs though the fire wall passenger side below the A/C system. Usually has a plastic cover around it dew to it bring so thin. but if it breaks you’ll only get air in the defrost or if it get unplugged from the canister..
I will take a look and see what i come up with
Thanks for the info. Now if you know of or know someone who can solve my draft under the dash problem on the drivers side I would be forever grateful. It gets damn cold on the legs in the winter and that will be here soon too! :0(
awesome, thank you for the nice comment 🙂 stay cool ;)
You are my personal hero – I would have had a real hard time finding this without your help! You showed me where to look and sure enough it was the problem. I too used 1/8″ aquarium hose to make a quick patch. To do the repair right it will take about 30″ of 5/32″ vacuum hose but for now the aquarium hose is keeping me cool in the 97 deg. heat! YAY
thank you for the positive comments, cheers
Yeah I did. Turns out the vacuum hose was cracked and ripped at the t-connector near the passenger side. Thanks, I was so glad I found your video:same problem and same vehicle!
did you get ther van fixed?
cheers
I’m currently having this issue on my van. Thanks for the video. At first, the symptom was that I would loose air blow while accelerating, but now it’s only blowing through the defrost vents
