The high speed setting on any blower bypasses the dropping resistor completely so I suspect you have a failing switch contact. If you can access it, some 'contact cleaner' from an electronic supply outlet may help to restore its operation but generally, once a switch develops problems, it will fail again.

My 2008 dodge ram temp gauge goes from normal to high ,check gauge lite comes on in a few minutes temp gauge goes back to normal but heater will only blow cold air I,ll shut heater off wait a few minutes...


Souds like it's way low on coolant. The heater will blow cold air when the cooling system is so low that there is no water (coolant) running through the heater core. Then the thermostat opens, it trys to be normal but the system is low so it gets too hot in just a few minutes. If its that low, there must be a leak somwhere.

1997 jetta ac works for one minute then warm air blows


check the refrigerant level. The compressor is running until the low pressure or high pressure switch switch cuts it off.

Running the unit without enough refrigerant will damage the compressor because the lubricating oil is dissolved in the refrigerant. This is the reason for the low pressure switch cut off--to protect the compressor from damage.

If pressure gets too high, the compressor seals will blow. Thus the reason for the high pressure switch. Too much refrigerant or too much air in the system (due to a leak) will cause high pressures.

If refrigerant level appears to be correct, then suspect trapped air from a leak causing a high pressure cut-off. If refrigerant is low, suspect a leak causing a low pressure cut-off.

Switch the relay with one of the other relays to make sure that this relay is good then go to the HVAC control programer which is behind the floor vent (middle). The Blk/gray wire is the one that supports the relay coming out of the HVAC programmer, but there is a chance that this programmer is bad. If that proves to be the case, I may even have one...let me know.

If there is a restriction in the a/c system, the pressure may be getting either too low or too high for system to work properly.

Also, if the charge is low, the compressor may not turn on 20 minutes into your trip.

Check to see if the pressure on the low side is 25 psi to 45 psi when running the a/c.

Good luck.

A/C suddenly blows hot air usually when idleing


it could be the a/c clutch is starting to go. They usually run ok for about an hour and then cut off. Sometimes you can shim the clutch so it is tighter, or just replaqce the clutch. Sometimes you have to remove the compressor to replace the clutch.

You may have an air pocket in your system which some times happens.  One way to get rid of it is to take the upper hose off on the engine side,  fill your system with water until it runs out from your engine block, replace the hose, start your car turn you heater on and set to hi keep the radiator cap loose until the temp start to rise then close tight.  Once the air pocket had been remover you can drain some of the water from the radiator using the lower drain plug and add antifreeze.
