Suzuki Samurai Heater Control valve.
There is nothing worse than getting into you Samurai on a cold winter day and not having heat.
The problem with Samurai heaters are well known, but almost all are easy to fix. One of the major problems
is that debris builds up in the air box from the open grill on top of the car. This box has to be cleaned out and at times
that debris will get down into the main air box under the dash. This can usually be cleaned out by removing the feed hoses.
Often there is no hot water flowing to the heater core. The valve that controls this is on on the firewall next to the battery. You can try to lube up the
the control surfaces but sometimes it is just too late.
