The black rubber elbows on the interior heater ducting has corroded. Was wondering what you guys use as replacements?

Man A Fre has the whole duct assembly but it is rediculously expensive at over $200.

Any suggestions?

One of the defroster hoses was missing when I got my rig. Rather than shell out dough to $OR or somebody, I went to Lowes and picked up a black PVC 90 elbow, a roll of Shop Vac hose, and a rubber coupler for the defrost plenum attachment. I made a defrost hose using these materials and it not only works great, but it was much cheaper and looks almost identical to factory (it will probably last longer too).

Love to see pictures of the setup.

Here you go. The flashlight gives everything a bluish tone...in sunlight it is solid black.

The 90 is a press fit on the heater box and the hose is also pressed into the 90. The rubber coupler (behind the dash and on the plenum - not in the pic) is attached with hose clamps to the plenum and hose. I have been using this for a year now and nothing has come loose. Trick is to find the right diameter 90 and hose so that everything wedges together (the metal outlet on the heater box will 'dig' into the PVC for a tight fit).

I still have the factory hose on the passenger side. There is no difference in airflow between the factory hose and my home built unit.

Well I got it taken care of! Bought the 90 degree PVC elbows at Home depot. If you want to spend about $40 to $60 you can use 2.5" 90 degree silicone elbows from auto parts store!

$3.95 did it for me! I only had to use a barrel sander to take off about 1/16" off the inner diameter for a perfect fit. I put some black silicone on the fitting to prevent air escape. Now my heater puts out!

Thanks WEAGLE99!!! Great cheap fix that works!
