The Heater in my sister's '97 Jeep Cherokee isn't working...?

Question:
So she took the motor for the heater out.."fixed it" and when she turned it on in the house it gave off heat..she put it back in her Jeep..but now it isnt working. What could be wrong with it?

2000 Impala, blinker works sometimes, on and off, is it a circuit?

Interesting - how you turn it on in the house? Have a 12volt battery on the kitchen table?...lol...just kidding

Checked your fuses, relays?

car petrol!?

Get an volt/ohm (multi-) meter and see if the wires in the Jeep are supplying any power to the heater. If not, then you have to check the switch. See if there is power going into and out of the switch. If power is getting past the switch, then guess what - check the wiring from switch to heater.

how much resistance does a 100ft of #10 wire have?

Think of electricity like water flowing thru a pipe - you have to find where the "blockage" is.

Do you know if one can remove A frame from Elddis caravan if so tell me how?

And - kudos to your sister for being able to get the heater out.

my NO emmisions rose from 800 ppm to 1200 ppm after I installed a new EGR. Why?

The blower is one thing and when testing it outside of the car, you are bypassing one important electrical component, the rheostat. This is a regulator/resistor that controls the amount of electricity going to the blower and therefor the amount of airflow. If you hadno problem R/R the blower, you should have no problem with this. Nice to see a gal get under the hood, so to speak.

I want to buy a 12v automotive battery charger and need some help.Any suggestions??

Edit: I agree with Lonnie. ;-)

What would cause a manual transmission car to lose clutch control and also simultaneosly not start now?

Judging from your picture, I would suggest having you ride in the jeep with her. Your hot enough to make it sweltering in there! Lol. Most likely a fuse or ground problem.
