Troopy Heater

Bruce toyota heaters normally work very well is the engine temp normal . Is the thermostat working ok. you should feel heat from the heater within 2 minutes . is the heater tap fully opening.if all the above is ok ,maybe the heater core is blocked . hope this may help

Thanks Larry. I am leaning towards a blocked core as everything else seems fine.

Bruce ,is this vehicle on lpg ? If so check the lpg convertor hoses, sometimes they are connected into the heater hoses and the water takes the least resistance route usualy the lpg convertor so the heater will not heat up. You may have to redo the hoses to the lpg convertor.
