Electric probs

[VolvoFox]

Hi

i have a litte problem at the last days. I had this problems a few month ago, but they have gone away alone.
now is it a little bit extrem

my problem is :

i start the engine and the car is running, i turn the lights on...
i blink left and the car close itself.
i open the car.
i go on the brake.
the car close itself.
i open the car.
i push the button for the window heating.
the car close itself.

if i don´t have the lights on then this problem comes only if i turn the window heating on...

a few mounth ago the car has open and close itself in tact...

and the lamp for the light test turn on. like when you go start the engine and brake and it turn off.
when you brake the lamp turn off to, but when the window heating is on, then the lamptest won´t get off.

what can it be?

maybe i go and make a video tomorrow...


greetings david

Massa probleem?

Check all relays above the pedals (remove the dash cover, 3 screws for 850). Preferably remove them and reinstall accordingly. Do the same for the relays next to the fuses (remove relay cover, 4 screws). While working there you might want to check the fuses as well (remove, clean, reinstall). One at a time of course.

Check both earth strips from the exhaust side of the cilinder head to the firewall, the blue connection between battery (negative terminal) and chassis point between battery and headlight. Repair or clean where neccessary.

If the behaviour persists, slam all doors, including trunklid, harder than usually. Measure the voltage on the battery when the engine is idling. And the same when you rev it up to about 1500+ rpm. Post the voltages here.


Good luck!
