I already had my main questions answered... The speeds on my heater fan quit working except for high & I was told it was the resistor.

Now a day after I posted that question, I noticed that when came to a stop it would start to blow cold & when I would warm it up in the morning or afterwork to head home it wouldn't warm up till I actually started driving... Will the resistor fix this issue also? Or could the main problem be something else?

 

No the resistor won't fix that it will just give you all your speeds back. You might want to try flushing your cooling systems out, specifically your heater core. Seems to be a big problem with the XJ's

 

OK first things first. Make sure you have enough anti freeze in the radiator then "burp" all the air out...Tj

 

Good call... I do go through anti-freeze & it's been a bit since I topped off...

 

Since he has a open air system wont it just burp out in the reservoir tank as it runs
