Sounds like you need a #3 temp actuator , it controls the temperature at the vents for the rear passanger, you should have someone scan the codes in the hvac controller

Front a/c blows cold air but back is blowing hot air


Could be low on freon, a faulty expansion valve on the rear system, or other issues. Can you tell if the rear ac lines are hot and cold ?

I have a jaguar x type my a/c blows hot on one side cold on the other. The it blows heat on both sides then back to hot one side and cold on the other


1st you do realize that the zones on this auto are adjustable from side to side not just front to rear??? , 2nd this auto has an electronic temp control that auto selects whether or not it blows hot or cold on that sides seating area biased on the temp settings of the person in that seat (body temp) , I guess its possible that the dash control module for this could be defective , but its been my own experience that if no one is sitting in that seat it gets a little "confused" and seems to cycle between cold and hot , one can only feel this if you direct all the vents towards the drivers side , simple fix is not to cross direct the vents over to opp. sides , as it will maintain (if working properly) a comfortable setting on drivers side (what ever set temp is )

How can I determine if my compressor is out on my


If you still get cold air out of the rear vents but the front only blows hot air you may have a bad temp door actuator in the dash, it may be stuck on hot and not able to move to cold air. However if you are low on freon with a truck that has front and rear ac then there will be a temp diff between the two. If it is hot air out the front like the heat is on then you have that actuator problem but if it is cool air about the same as the outside air temp then you may be low on freon.

A/C not cycling and blowing hot and cold air.


Hello msbrig,
This is a REAL SWAG
(stab in the dark... (a bit reasoned))...

Confession... I'm no GM expert... but
General Motors & FRIDGIDAIRE
are the "GREATS" in automotive A/C.

and

This is the BEST DOCUMENTED QUESTION I have
ever seen (congratulations)...

I hope I am not doing a disservice by attempting an answer...

If your vents blow al any time... you ought disregard their behavior.. Likewise temperature controls...
and DUAL EVAPORATRS... front & rear...

The fact that your troubles are intermittent in the FRONT & REAR is a really great SYMPTOM...

You are MOST LIKELY looking at only two POSSIBLE PROBLEMS....

1. - Either your CHARGE is insufficient to keep
the compressor running.(pressure switch monitored)

OR

2. - You have a SATUATED DRYER which is allowing moisture to block your EXPANSION VALVES (internal ice) ...

External frosting is expected...
a lot of external FROST is an indication of #1. (above: low charge)...

A descent refrigeration person should be
able to tell you the HIGH and LOW pressure loads... and watch your system cycle for a few minutes... Which should be long enough to DETERMINE if you are experiencing
INTERNAL MOISTURE ISSUES...

Some folks ROUTINELY replace the ""DRYERS' (desiccant)


I do not... I use brains, gauges, experience... and your vehicles HISTORY

I am here most every day... Push comes to shove... I have the
Lincoln Navigator... dual EVAPORATOR system...
(I'll pull the book & take a look).

You can comment me back...

I bought ALL THE TOOLS years ago... NOTWITHSTANDING my amateur standing... I only let the JAGUAR DEALER jam me for an $800 Schrader Valve since 1965 (Mustang(all the rest... I did myself)).

Happy to chat... comment me back.
(again: here daily)


- Hope this inspires...

2001 tahoe front heater not working, rear heater blows warm air


Notorious for plugged heater cores. Also updated plastic restriction couplers mounted at heater core available from dealer. Try back flushing heater core. Run engine till its at operating temperature then carefully hold the inlet and outlet hose breifly with heater fan on high if hoses are nearly the same temp then flow is good , if not then core is plugged.

Climate control panel


These problems are usually caused by a faulty blend door actuator which controls the position of the air mixing door, and in vehicles with more than one air zone (passenger/driver, front/rear, etc.) there will be a door/actuator for each. These electric blend door actuators are self-calibrating - there is a feedback circuit (wiper type potentiometer) that tells your HVAC control the position of the door. It is not unusual for this potentiometer to wear causing loss of signal at various positions, which then will cause erratic movements of the door (if the circuit fails to open circuit or shorting, the door will default to fully open or closed - i.e. hot or cold air only).

Heater only blows hot (well, warm) on full speed of fan


Replace the temp control on this car, it should be electrical control not cables.
