change ignition on a 1989 buick reatta

There will be no plug you have to drop the transmission pan. But the real issue may be 1st gear is failing so be prepared for a transmission rebuild before it completly goes out.

hello the only thing i can think of is that motor for the lifter is at fault, the motor has a set of switch on them to stop lifting and dropping if one of the switches has gone it will go off cog and be stuck as its a cog system you will not be able to move motor by hand. i would remove the motor and check to see if you can get it to work on a external power source. hope this helps

There is no relay.....there is a motor controller. located in the duct work, on the firewall, passanger side. it has two connectors and 3 screws that hold it into the ductwork. Common problem is the fan will not shut off when the ignition is turned off.

The headlight gear seldom is bad. the problem is the arm on the motor and/or the connector rollers inside the motor. Replacement kits are on Ebay that fix both. The lights not working sounds like a bad headlight switch. Riviera used the same switch so they are not to bad to find.

Either the speaker is messed up or wiring to the speaker is broken somewhere or the radio itself is broken in that channel only and needs replaced.
