No heat

check to see if the valve on the heater hose moves when heat is adjusted cold to hot. you may be able to hear coolant moving through the heater core if the valve opens. good luck. hope this helps.

My heater doesn't seem to want to get hot. I have done a radiator flush with new antifreeze, changed the thermostat and it's still blowing out hot air.

If it's not blowing out hot air, the blend door may be the problem on the 1990 Isuzu Trooper.

Heater Water Control Valve REMOVAL & INSTALLATION On early models the heater control valve was part of the heater core inlet. To replace the control valve, remove the heater core as outlined in this section. Remove the control valve from the heater core, being careful not to damage the core. Use new gaskets when installing new valves. The remainder of the vehicles are not equipped with heater water control valves. They use heater unit doors to regulate the amount of heat entering the vehicle. --- I would check that both tubes running to the heater core are getting hot. If they are, then there is a blend door problem. If both tubes are not getting hot, the heater core is blocked somewhere or the heater control valve, if so equipped, is in need of replacement. Good luck on this repair. prev.gif next.gif

1986 trooper isnt putting any heat and isnt blowing at all

check the fuses for the fan. could be a blown fan motor, bad switch...or maybe water heater core bad, hot water valve bad, disconnected heater lines in the engine compartment... all possiblitlies
