Note:
If performing the above procedure does not appear to correct the condition, a gap at the back of the dash, where the dash and cowl assembly
come together with the windshield frame and plenum assembly, may be the cause (see Figure 2). When these two pieces are welded together in
production a gap may be created on the vehicle. After
the welding process this gap, as well as the rest of the joint, is sealed. If this gap is not sealed properly a howl condition can occur.
