Hello.
I have an 86 corvette and am starting to have a problem with one headlight not opening, but when using the manual open **** and then hit the lights the door shuts fast.
will shut but not open.
is this a relay issue or with the motor.
second part of this is i bought some complete headlight assemblies from a 84 corvette and the motor has only two wires instead of the three wires on my 86.
can i get these to work on my 86 .
what years are compatable to swap for the headlight assemblies.
i saw some on the 90's model year i think have one five wire plug for the headlight & motor together.

If the 84 only has 2wire motors it sounds like it was converted to a later style motor.. 84-87 motors were the same.. There is a kit you can get to convert the newer to the older, Mid America was one but they are out of stock.. Here is a link with an instruction manual on their site..

If you click on the installation instruction section you can download the pdf file.
Was there not a kit included when you bought the assemblies?

I think 84 to 87 are the same 88 to 1990 and 91 to 1996 are the same. If you have a 84 with 2 wire some one upgraded to an 88 up motor

No kit was included, the headlight assemblies were pulled off the car by the seller before i arrived.
thanks for the link and the information.

thank you for the information.
maybe i can get these to work on my car.

to me the best option is to get 88 thru 90 motors and by the upgrade kit from a vendor on here. This way you do away with all the relays. and a lot of problems it semplifies the whole operation

I went back and retreived the kit with the controller and the adaptors.
is there any way to get ahold of the instructions for this kit.

The link in post # 2 has the details on how to convert the early 3 wire setup to the later 2 wire

If one bucket works properly and the other doesn't, you might have a bad motor or the wires at the connector at that motor may have gotten corroded or have broken.

When the harness connectors were assembled, a heavy black sealant was used to keep water out. This sealant will have gotten real hard over the years and movement of the connector may have caused corrosion or the wire has come loose from the brass contact inside the connector.

Because the early headlamp relay system uses an isolation relay to change current polarity, it's possible that the motor that's not working isn't getting any power to raise the headlamp bucket. Because it goes down, the motor itself is working. I would suggest checking the connectors and cleaning everything before buying a motor that may not be needed.

When i click on the assembly instructions it only shows 1 page on mounting the control box to the fender well.
even when i download the attached file.

I had this same problem this past year on my '86; the right Headlight would go down but not up. I replaced all 3 Relays; they were originals anyway, but it was the Motor that was bad.
