NoVA_69_442

Was hoping someone might have some insight to this problem. When I turn my heat or AC on the high position I get nothing. On the first three fan speed settings it works fine, once I get to that high setting it essentially shuts off.

Any ideas? Its a 69 442 with a vintage air setup.

Not knowing how the Vintage Air system is wired, it's hard to provide a useful answer. The factory A/C used a separate power source for the high speed blower position as opposed to the lower speeds. The factory system has a high speed blower relay and a separate 30A fuse, either of which could cause a lack of high speed problem. Again, not knowing if your VA system is wired the same, it's difficult to know if this applies.

Hey Joe, thanks for the response. I’m bringing the 442 out to the show Saturday, I’ll chat about it with you there if you’ve got some time. See you Saturday.

Great. Seeing the installation will certainly help.
