The upper 3 lines on the rear window glass are the AM radio antenna, the middle 8 are FM and defroster, and the bottom 8 are defrost. The amplifier and the rest is behind the C-pillars of the car. For the rear window heater on drivers side, but also some is on passenger side. Just remove the covers from the C-pillars.
That is behind the c-pillar https://www.ebay.com/p/BMW-E32-E34-O...540/1622691246
More details here http://shark.armchair.mb.ca/~dave/BMW/e32/

Check the fuse box under your rear seat of the E32, because there is also the fuse for the rear window defogger and that goes the same route via the C-pillar and this fuse is known to cause fire or blows.

I said above already, more details here, see page 6420-04, nice drawings and explanations what is where http://shark.armchair.mb.ca/~dave/BMW/e32/e32_90.pdf
as you do not give us much details on the car, just 1990 E32, it could be either the simple antenna or the diversity antenna, but all explained there
Horizontal antenna: upper 3 lines = AM/FM
HZG = Heizung = rear window heater
here you see all parts Diversity antenna and normal antenna, scroll down http://www.realoem.com/bmw/enUS/part...MW-735iL&mg=65

vertical: upper line which goes in the middle down is FM
The next 3 lines are then again FM/AM
Then several line FM/Heizung (+)
Then at the bottom HZG = Heizung = heater (+)

Fuses: all details for each fuse start on page 0661-00, rear defogger/antenna 30A !!! fuse is under rear seat #46, also 21 and 29

Check that fuse!! Important https://www.bimmerforums.com/forum/s...fire+rear+seat

For carsoft check Ebay for example

Looks like something broken inside that amplifier. Those 3 upper lines suppose to make a heat for window.

[shogun]

the 3 upper lines are antenna lines for AM/FM, see page 6420-04 in the ETM. Below the AM/FM lines is heating

[Annddrriy]

I already saw 6420-04 it doesn't say anything about 3 upper lines for heat defogger. My question is why in my car 2 upper lines not working ?

[Annddrriy]

It also says on amplifier in germane languege heizung witch is mean heat defogger. Looks like something broken inside that amplifier

That is the problem the 2 upper lines not broken they are still ok.

somehow I do not understand your problem. Above you say not broken, in your first post you say

Upper to grills not working

And again I am asking you: did you check the fuse 46 under the rear seat?

[Annddrriy]

I did recheck.3 upper grills not working and I still don't understand if those 3 upper grills antenna and grill or just antenna? Fuse 46 ok.

[shogun]

the 3 upper lines are antenna. details here, see page 6420-04, nice drawings and explanations what is where http://shark.armchair.mb.ca/~dave/BMW/e32/e32_90.pdf

Horizontal antenna: upper 3 lines = AM/FM antenna

HZG = Heizung = rear window defroster
