Strange Problems with EK3

[khandman]

Guys, had a strange holiday today. First, when accelerating above 80km and i release my foot from gas, Tip brake or mash clutch to gear up or down, tach and spedo drop to 0 and radio cuts off. but just for a half second. then normal again. happened a couple times today.

Second. Serviced AC like a month ago for most. working great and blowing cold. Used it today, went to Gulf city, park up and eat with ac on working good. left and drove to oropouche, working good. cut off and restarted like an hour after no ac. Hearing it come on everythin, but no air coming from vents. none of the vents. took off ac and tried fan alone, still no air.

Please offer any advice on the above. thanks

sounds like an electrical prob bro , better let the professionals check it out. The ac is as a result of the blower motor not comming on ..

Your first problem is IAC valve. Service trottle body including IAC valve. If no difference after this, replace trottle body.

Your A/C problem is your blower card. Once the blower is not coming on the compressor would not run. It needs signal from the blower to turn on compressor and engine fans. The blower card is located under you dash behind the pocket. You have to remove the pocket and scrap part of the dash to get to it. Remove the blower card and replace with exact type only.

I would check the battery poles just to be safe

Loose battery poles can really f-up your ECU

Also check your speed sensor

How is this done?

happened to me already. Tipped brakes and all gauges dipped for a split second, including radio cutting off.

Grounding. I cleaned all grounding points and battery poles.....problem went away, never seen it again.

Guys, thanks for the help. was indeed grounding and also loose battery poles. I feel like such a noob for having loose battery poles. AC seems to be blower motor. taking it out tomorrow. Hoping its just brushes. Thanks for the help
