Have a 74 maverick 2 door 250 six with air conditioning ,having an issue with venting that everything blows to floor an nothing to windshield for defrosting? Had a heater core replaced recently ? Any suggestions on how to get all venting to work . Thanks
The doors are actuated by vacuum. The hoses enter the firewall near the heater core. You should see a rubber plug with several lines running inside the car. They go to a distribution block on your heater control. Check for leaks. Micah
Normally the default setting , if there is a total loss of vacuum, is to the defrost setting. Strange that you are only getting it to come out the floor vents. Having said that, I would still look at all the vacuum related items. There are several vacuum motors/switches and lots of vacuum lines under the dash.
He mentioned had heater core replaced; whoever had box out should have inspected all that while working on the unit.
Thanks Craig I have to check it all I get full blow to flooring no where else now car came from texas maybe previous owner did some so he had air conditioning blowing full to floor area???
Either a vacuum line is disconnected, or your vacuum storage canister under the hood likely needs replaced...
I have a good look at it thank you. I'm just wondering when I had it in garage to have a new heater core installed they disconnected something an didn't bother to re hook up?
Hi Craig off post question do you still sell part I have got some off you in past what I'm looking for is the centre link for the 74 maverick with power steering they are pretty rare to find in Canada if not at all seems lots for manual steering but none for mine with power steering?
