Heater Problem
My A/C works great, no leaks from my heating/cooling system, but my heater won't blow hot air. No matter what setting I put it on it just blows really cold air (even in the summer).

I think it might be the A/C Heater Control Switch (from what I've read on here)

Having trouble locating the switch on my '98 XJ. If anybody can tell me how to replace it or any other suggestions for my problem it would be greatly appreciated. Thanks.

Are the hoses running to the heater core (on the passenger side of the firewall) hot? You may want to search for "blend door" for a fix for that issue as well.

Thanks for the reply, I followed the advice from djflyy (below) and it seemed to work out, finally getting hot air and not a moment too soon, it's getting cold here in San Antonio! (31* is cold by my standards). Anyways I'm gonna do a whole radiator flush next time I get the chance. :highfive:

Thanks again

Don't forget to spray through the radiator to clean mud out of the fins. :)
