RE: NO HEAT / Climatronic
Check the engine coolant level. The level must be full to circulate through the heater core properly. If the coolant level is correct you need to find out if the “Hot & Cold” control is operated by a cable or a vacuum line. Something may have come unhooked. If you need more help, let us know.

Please let us know what you find.
Thanks, Garner

RE: NO HEAT / Climatronic
What part doesn't work? If it doesn't get hot follow what Garner said. If it always blows out the defroster vents on top of the dash that's what they call the default mode (for safety) and there may be a simple solution like a blown fuse or vac line off. OTOH, it could be a failure of the heater control itself.

RE: NO HEAT / Climatronic
Garner,
Thank you for your response to my question, it was in fact the fluid level but taking your lead I flushed the heater core and the entire cooling system and replaced all with new antifreeze mix (RED). When completed I also air bleed the system and now all is working very well with the heat. Again thank you and "Rupe" for the great advise

Regards,
Subsea Mike

Mike,
I really appreciate your response. We respond to so many questions that we never hear an outcome. It’s really nice to hear what the “fix” was. Glad to hear that your problem is resolved! One last thing to keep an eye on, if the coolant level was low, where did it go? Keep an eye out for a possible leak. One spot that nobody looks for a leak is in the transmission. If the fluid is getting “milky” get it fixed quick! Water destroys automatic transmissions.

Thanks again, Garner

Hey Garner,
This is a great forum and just think of the Money saved on this one single item. I would have never thought to check the Trans. fluid for color, I did check the engine oil and it's good, also checked all external areas and found no leaks. I will change Trans. fluid today and post results when I can. Again thanks for the response and hope you and yours have a Merry Christmas & Happy New Year.

Hey Garner,
I'm Back !!!
Well it seems I was premature with my fix concerning the Heat Problem, I have tried everything my friend and the thing I really need to know now is "WEAR IS THE HEATER CONTROL VALVE LOCATED" I can not seem to get a hand on this thing. Can you please tell me, it's like trying to find an Easter Egg man.
Regards,
Mike W.

This may help..... http://www.autozone.com

They have a component locator section with diagrams for many popular cars so you can figure out where things are. It's a free site but requires user registration for some of the features.

BTW, before jumping to replace the valve try following the vac line (if it has one) to see if there are any breaks or cracks. Matter of fact I would look over all of the vac lines just due to the age / heat factor. IOW, the line to the valve may be ok but the line that feeds the heater control may not be ok.

RE: NO HEAT / Climatronic
Hi Rupe,
Thanks for the quick reply Smile. Well I thought I had this solved but I still have no heat, I have as you suggested been to Autozone and that's okay if you own American but no use for forign cars. I will continue looking for this phantom valve. I have replaced all of the Vac lines but I will recheck everything again. I think it's going to wind up being Electronic, I have good heat at the core but nothing in the cabin and as you stated before when the system is turned on it goes straight to Defrost with only cold air. Get back to you again soon and thanks again for your time. Oh yes and there was no water in the Auto Trans.

RE: NO HEAT / Climatronic
Those last two points are probably worth repeating with someone who works on these things daily. (defrost only and cold air while the core is hot) I would go to a dealer to price the control and ask someone while there. Maybe buy someone a cup of coffee for a few minutes of their time during break. There's nothing like experience with a particular model to sort things out.
