Over heating when the aircon is on

When your A/C is on it puts an additional load on the engine. The throttle positioning solenoid pushes on the throttle linkage and increases the idle when A/C is on. Some are electric some vacuum You need to check and make sure its not stuck, plunger should get a shot of WD40 and move with finger to work in.
Make sure the connection is good Vac or Elect WD linkage also

Hope this helps Mike

Anytime the A/C is on, one or both radiator fans will be automatically turned on, and run as long as A/C is used.
Check a wiring diagram, you might be able to troubleshoot it. Relay terminals are a good place to check for power or loss thereof.

The smell is typical of older Mazda aircon.
Purchase an aircon cleaning spray which is discharged into the aircon system by selecting recirc , cloing the windows for 5 minutes . This cleanses the system which is probably contaminated with bacteria.
Recharging your air con will help as well. The smell is due to evaporate condensed water mixed with sludge and bacteria .

change the antifreeze and flush your system, its been hot lately so the motor heat goes up too, having the AC on makes the motor work harder, so thats normal that the temp would rise when its on. traveling on the road allows air to help cool the motor, sitting in traffic slows the air, so there again heat will increase

Check to see if you have an air conditioner fan which is usually fitted on the outer (grill) side of the radiator, make sure that works when you switch the air conditioner on when the temperature goes up.

DO NOT PLAY WITH SYSTEM ITS DANGEROUS take to air con dealer to diagnose the problem i worked on car aircon systems and have seen many accidents the only way is to check the high and low pressures ifits got the old r12 then it may need converting to hc134 refridgerant

this is most often caused by a slightly low charge of refridgerent, as the engine heats the system the gas expands and the light goes out.

mm sounds like the air con is in need of an overhaul take it to someone who specialises in aircon to be checked out hope this helps you

ok when ur sitting there no hot air is coming in to the air con radiator at front of car because your not driving
but when your driving it comes in but stays cold because the fan kicks in is your aircon fan working?

or does it need more gas thats what else can cause this

The econ button allows you to set the heating manually, With this button pressed only manual heating is on and aircon is off.if you want heating and aircon off press the OFFbutton
