engine and drivetrain No Heat in Car

[jgerock]

You are 1/3 the way into pulling the heater box. I highly recommend doing it now that you have the heater hose and valve out.

You can fabricate a simple angle-shaped piece of aluminum that bolts or rivets to the plastic fan cover (totally eliminating the stock mounting tab).

Installing new heater hoses (especially the short one) will help secure the valve in place. The large grommit in the bulkhead will also help. Old stuff will most likely flop around.

It really isn't that hard to pull the box from your car (no A/C helps!). I just did this yesterday to a 74. ALL of the control cables and wires do NOT have to be removed from the levers. Only (1) wiring connection at the front of the heater box has to be disconnected.

Also something others have not mentioned. if the heater core is full of crud you will get no heat, even with a new valve - no water flow = no heat.

I replaced a valve a while back and it made no difference. I finally pulled the box, had a Rad shop cleanout the core and now I get melting socks like Mike. Just thought I'd mention it. Beaner7102

I've already put everything back now. The lever works perfectly and I will test the heat tomorrow. I think i'll pull the box out when i change the blower fan at a later date. Interesting thing is that when i switch the fan on i hear a click and i see my volts go down as if it's working. Does that make sense? The fan just doesn't move.

One of the (2) wires at the fan motor may have come loose - or the motor may be kaput. My fan motor was brand new about 10 years ago, but was hardly used. I had to replace it again along with the motor cover and fixing some old re-appearing cracks in the housing with JB Weld.

I don't need to turn the fan on in my car with the heat lever about 1/2 way "on". The outside air makes the fan turn and blow air thru the box. Shoe-melting heat in my car. I have to open the vent window.

try spraying the fan with some lube and reach in there with something like a long screwdriver to try and spin it...it might just be stuck...mine's been like that a couple of times because it seldom gets used...a bit of pb blaster & a nudge always gets it spinning

hmmm, i'm in los angeles so don't really need heat that often or that intensely. i just like to have everything working on my cars. so i guess i'll tackle the fan eventually.

if the motor is bad would the volt meter still react as if another device was switched on?
