Question about 1990 Mercedes-Benz 190

2 Answers

The ac compressor on a 190e 2.6 does not come on.

I applied 12 volts directly to the compressor and it will run so I think it is ok. I checked the relay and fuse. They are good. It does have a freon charge. Also jumped out the pressure switch. What should i check next? Thanks, Bruce

    I am not 100%sure but there is a clutch kind of a ring that might have gone and it is not engaging, check it as well.

1983 Chevrolet C10 Silverado: The AC compressor and heater blower motor fan will not come on.


The brown wire at the speed switch is the power wire. Powers is then directed to the blower motor resistor throught the orange, lt blue and yellows wires. The blower motor receives power through the orange wire. Check for power at the fuse with the key on. If there is no power the problem could be the ignition switch or the wiring in between the switch and the fuse block

Spin center of compressor by hand if ok, check single wire to compressor for 12 volts with ac on, if no voltage is present double check your refrigeration refrigeration pressures, you may have overcharged or overcharged the system either way the low or high pressure switches could be bad or indicating a problem with the charge

COMPRESSOR CLUTCH NOT GETTING POWER? COULD IT BE THE RELAY ?


First item to check is if the refrigerant has enough pressure. Low levels of fluid will damage the compressor, so the system protects itself by not allowing the compressor to operate. (It cuts out the voltage to the relay/ clutch. If the pressure checks out ok, then check the relay and associated wiring.
As a last option check if the clutch is working. Do this WITH THE VEHICLE TURNED OFF, by applying 12 volts directly from the battery to the clutch terminal. You should hear a loud click if the clutch is working alright.

1993 accord ex ac not blowing cold replaced compressor last year freon level ok unit not engaging is there an easy fix?


With the engine turned off, test the a/c compressor clutch by applying 12 volts to the contacts. You should hear a click of the clutch engaging, and if not, the clutch is acting erratically.

My 2005 ford ranger a/c is not working all the sudden, could it be a fuse?


My AC quit all of a sudden and it was a switch in the ac line. It was located on one of the air conditioner lines almost next to the firewall. Looked like a little box. When the p/u was running and the ac was turned on, I tapped it with a screwdriver handle and the ac compressor came on. I think it was a low pressure switch and is supposed to keep the ac from running without any freon, so you might try that. Best of luck.<!-- from fixya rte -->

Ac compressor clutch does not have power going to it. Clutch relay is energizing and both pressure switches are closed. Is there any other device that can break the circuit? 1997 dodge ram 1500


You most likely have a wire .or connection problem,the ac clutch relay directs 12 volts directly to the ac clutch,if needed,find the wire,from relay,to the ac clutch,and run a new one to correct the problem,if his was at all helpful please rate,thank you.

Ac problem


Static pressure(Non operating) usually is around 70 lbs and should be even on both sides. Sounds like the systen is too low for the computer to allow operation. I suspect a small leak somewhere. Adding as little as 1/2 lb should allow operation and leak testing.

Ford f250 a/c stoppes cooling when driving average speed


I think either the pressure switch that turns the AC compressor on and off is at fault or the magnetic clutch on the compressor is going open when it gets hot, when it stops working use a 12 volt test light to check if 12 volts is present at AC compressor connector, if it is'nt check the cycling switch in the low pressure line, that is the line that gets cold and is the largest size coming from the compressor, it may also be in the accumulator bottle.
