Default Blinker slowing down with tail turn on

Hello i've an issue with blinker on my corvette c4 1995 lt1, as matter of fact i don't know if is normal or not....
I think not

Well

Blinker has normal speed when tail and parking light turned off

Turning on tail and parking light then engaging the blinker these flashing more slowly

Do you know why?

I have already replace bulbs 1157 with 2057 but this wasn't the reason

Thank you guys

The only thing I can think of would be the Blinker relay, or possibly a ground wire is loose not making good contact....WW

Don't order anything until you confirm a couple of things.

Do you have the conventional lamps for stop & turn OR is this an EXPORT car? There's quite a difference in the wiring, if it's EXPORT lamps were the lamps added or is it actually an EXPORT car?

On the SPID label there would be a T90 if it were originally an EXPORT build. I believe in '95 the SPID label was moved to the storage compartment passenger side behind seat BUT there are occasions when it's been mentioned console door.

The battery may be old, weak or sulfated. Have the battery tested.

The charging system may be marginal have it tested.

@wvzr-1
my Corvette actually has an American oem tailight...
I don't know if in the past was an European taillight installed on
There's a grey single wire not engaged in the tail section and no other, but I have four red blinkers

The spid is side passenger storage I will check it later, I'm not with car now

@church key
Seems that the battery is new.. With the engine cut off it has 12,6 V, when I turn it on voltmeter on cockpit reads 14,2 14,4v

Does the power antenna work? The only gray I'm familiar with is a gray to I believe the relay. There certainly could be more gray but it's all I recall. Where is it? Center of car, left or right side? Behind the bumper fascia or in the storage compartment. What all doesn't work on your car? What happens when HAZARD FLASHER is used when the headlamps are turned on?

Power antenna works good, grey wire is on left side above the wheel fender inside, maybe that it was used once in case the car was equipped ( i don't know really)with euro tail...



some video link about blinker, to get a better idea

That's normal.
When the parking lamps are Off, if you turn the turn signal On, you
will see the side marker light and the front turn signal light blink at the same time.

With the parking lamps On and the turn signal On, the side marker light and the front turn signal light blink at opposite times.

This is due to the way the side marker bulb is wired. It has no direct path to ground.

If you want the same blinker rate with the Parking lights On or Off you need to purchase a Non Load Sensitive flasher.

Thank you Yes I know this I've read it on service manual...

I'm speaking about turn signal:
Front and rear turn signal blink 80 times per minute (without any other lamps engage) When I turn on parking and tail light turn signal go down 70 times per minute...

Suggest replacing the stock flasher can with a Wagner 552 turn signal flasher can.

I don't know how many $$ or what the shipping is for that flasher but it's used. I would think you could accomplish what you want to accomplish "locally" and I'd suggest you do that. Generally speaking flashers are marketed to flash 60 - 120 times per minute and it depends on the loads. You may actually have to try a couple different to arrive at a flashing rate that suits you.

You might ask what the required rate is for your safety inspections and what flashing rates your car builders use in your country.
