Greetings.
My 99 Accord blows cold air. Both heater hoses get warm enough. I found nothing on this site but found You Tubes about re-soldering the control board's capacitors. I was doing that when I noticed a jumper wire that connects LE8 (AMB) to someplace near LP4 but that end of the wire had come off and I don't know what to reconnect it to.
Does anyone know where to connect it or where I can find more info about this board. I'm not ready to buy a board until I try to fix this one.
Awww man! I thought I knew this one!
The heater in my 1999 Accord blew cold, but that was an open thermostat.
Here is a control board with high-resolution pictures: https://www.ebay.com/itm/153902672650
Apparently there are automatic and manual HVAC systems.
Does that refer to the transmission or the HVAC?!
So, that may be the wrong board?
I found LE8 (AMB), but not LP4, but that jumper wire does not sound original.
That jumper fixed one problem, but then he reported:
The blowers, and the HVAC is working fine now, but now there's only cold air blowing in the vents even when I have it on heat, and coolant is depleting very quickly. Also, I only see/hear the fans kicking in when I put the A/C or exhaust on.Whenever I drive for 10 minutes plus, I can see and smell the coolant burning off near the radiator. So I top off the coolant in the radiator and backup once every 30 miles. The temperature gauge does not raise, so I know it's getting the coolant and isn't overheating the engine.

Just me but it sounds like a coolant leak somewhere. Need to find and address this first.
Alimaxor replied:
Okai, I'll look for any leaks in the system.
and
I'll try finding the leak this weekend
, but he never reported back.
You may consider posting there. Hopefully someone is willing and able to assist you!
