How do you replace a control arm on a 1994 Mercury Topaz?
If you go to www.autozone.com , click on vehicle repair on the left, check the year, then mercury, then topaz. It will bring up repair guide for 84-94. Next click on suspension and steering, then front suspension, then lower control arm. Save this site, it's great for any repairs you have. You don't have to login, and there are detailed pics :)
Only the 2.3L HSC Inline 4 will fit in the 1986 Mercury Topaz. If everything in the engine bay were gutted, perhaps something larger such as a 3.0L V6 from a 1992-1994 model MIGHT fit but it would require a complete running 92-94 Ford Tempo or Mercury Topaz with the V6 engine as a donor car (and, if you could find such a car, it would be more worth your time/money to invest in it…
First of all if all your lights don't work then its your switch I was told on my 94 it was the switch when my tail lights wouldn't work but all my other lights did. if that's your case or vise versa then its a bad ground somewhere. If not there is some mounting hardware under the dash almost where your fuse box is.
