A few months earlier my blower because that my a/c started to only turn on when I would hit a bump or take trip over 60 mph. Currently it will not turn on at all. Also, before every one of this started, there to be a revolution noise comes from the passenger side of my car that would certainly come on and also off once I fight a bump. It would remain on also when i turned the auto off. However, this revolution noise stopped as soon as I started having the a/c issue. Is this an electrical problem? Is that expensive come fix?

perform you have an Auto Temp manage system?You did say that there was a duration when it would still run with the vital OFF, right?

Hisounds like it can be a blower motor going out/worn out. Carry out you do any kind of work on cars you yourself or family?

The revolution noise is what continued to be on v the auto off, no the a/c. No there is no auto temp control. The revolution noise can have nothing to do with the a/c problem. I simply thought it can be helpful.

Welcome to the forum, I"d have to acquire at the blower engine connector. With crucial and hvac rotate on, inspect for voltage and ground at the connector. If the checks out, I suspect a faulty blower motor. Any fuses girlfriend check, usage a testlite on the fuse circuit, make certain the circuit is hot.
mine blower pan does not work(for ac or heat) ns hear it, it just doesn"t blow. It supplied to begin working again as soon as I pounded the dashboard, currently it does not. Wherein is this heater crate duct? Also, to inspect for 12 volts the power, how do I execute this?
check batt main fuse 4-- 30 amp, in the underhood fuse box. Usage a testlite, the circuit need to be hot all the time. If the checks out, I"d have actually to gain at the blower engine connector and check for voltage and ground.
The blower fan functions intermitantly. Once it is no working, if ns hit the right side the the center dash (where the controls space located) it starts working. It likewise starts working if i hit a bang or pot hole. If it is the regulate module (contains 3 dial switches and also the rear dfrost and also air conditioner button) is there any means to check it?
Welcome come the forum. Have all problem codes checked, see if something points to the hvac system. I"d obtain at the blower engine connector, every little thing turned on, examine for voltage and also ground. If no voltage, i backtrack the circuit. Test once the blower refuses come run.
