heater control valve located on 2001 gmc jimmy 4.3l
How do you replace the heater core on a jimmy?
A '96 jimmy does not have a body control module (bcm), it does, however, have an engine control module (ecm) located ontop of the coolant reservoir.
Low coolant? Bad thermostat? Heater core plugged, restricted, or airbound? Temperature control cable not working?
Make sure the heater control valve is closing. Unfortunately, that can be a difficult process and usually involves disassembling the heater assembly under the dash.
Before CHanging the Heater Core, have you tried flushing it? I have a 99' Jimmy and have to do this every year to get my heater to work.
in glove box
Under the right side of the dash board, under the air ducts
Better check your title. Jeep doesn't make the"Jimmy". Jimmy is made by GMC, The blower control module on a GMC Jimmy is located in the heater unit which is a plastic housing located on the left (passenger) side of the firewall. However, Jimmys are noted for bad connections on the module plug , the motor plug, & some have another plug that goes bad regularly to the rear of the left fender well. You would be wise to check those connections before buying parts. Good luck.
Low coolant? Heater control cable not adjusted properly? Bad thermostat? Heater core "airbound"? Water pump not circulating coolant?

Under the hood , in the main fuse box. It should be a relay in the main fuse box , that is located under the hood.
