Sandy;
Have your battery cables load tested, this means to disconnect cables from battery, place load tester between batt post and pos cable and load up to rated cap of the alt. should not have more than 1/2 volt drop in pos side or neg side, I have found more problems on the neg side than the pos side. also check ALL body grounds. You are getting a feed back causing your goofy problems,a # of these items go through a thing called a GEM module, check the ground to this module.
Hope this helps you out,
Cliff

About the screwed-up instrument panel: One poster suggested we try a load tester-can you buy one? How much is it? We asked a Ford mechanic about the problems, he wanted to replace the alternator. We'd like to try every available option b-4 going that (spendy) route.
Suggestions ?

Ford Focus....lemon...??? by sandy18

Ok; we needed to have the alternator replaced in our '05 Focus. After shelling out $$$ for that, we bring it home & have the same problems..beeping, speedometer not working, etc.!!! The mechanic who installed it said it must be the computer. The warranty is no longer effective, but doesn't the consumer have some recourse here? Anybody out there with Focus problems, & what did you do? This is running into serious $$$$$ !

We had the same problem with our 05 Focus too! and we too dished out big bucks for a new alt.& battery! and then a new $60.00 ECM computer but the problem was still happening! we ended up shelling out another $1,100 for a new instrument panel and that fixed it!. Then 2 months later the car caught fire and burned to the ground.

I cleaned up the battery post connectors for probably the 2nd or 3 rd time, but also cleaned up the ground connections . So far , so good, but it has only been 1 week so I'm not holding my breath.
 
I will keep you posted

SVT has got me stumped by ladyfocus

Alright,
 
I have a 2002 SVT (it just hit 77k) About 10,000 miles ago, i had some crazy hesitation at 2800-3200 rpm. the rpm would not surge or drop the car just would pull against me, and be get a little jerky. well i changed everything i could afford in way of the fuel and electrical system (plugs and wires, altenator, battery, fuel filter) no help...well after visiting some forums, i figured out that it was an issue with the MAF and that all i had to do was have the computer updated at the dealer. i did and tada!!!! problem gone.... well about 1000 miles ago, this problem seems to be returning...but the hesitation is not nearly as violent as before and comes in more between 2800 and 3000...so really i don't know if it's the same issue or not, it is not nearly as consistent as before either,,,it won't always do it. I really can't afford to pay $100 every 8-10k miles if it is the computer again. i love the car and hate to give up on it.
 
I just want to know if anyone has any suggestions as to what this may be, or if they have had similar problems...if it is the computer again, should the dealer flash it for free since it's been such a short time? (if it matters, i have random dash lights on too, they've been on since i purchased the car at 48k, my traction control and brake light)

Someone just told us about checking out the computer---why didn't we do that right away..? So, that's what we will do soon, & keep our fingers crossed also. I'll post results; maybe it'll help someone else.

Door lock problem by ric041

I have been having a problem with the drivers side door not locking either with the key or the remote on a 2005 Focus. All the other doors lock, but not the drivers side. The car went dead the other day and I had it towed to the dealer. The car wouldn't start, but all the gauges would be flashing,interior and headlights worked. The dealer said there was a bad cell in the battery and replaced it. When I asked about the door lock situation, they said it was working . When I picked the car up, the first thing I checked was the lock. Not working. Waited around 3 hours for them to run a diagnostic but finally had to leave. Any ideas?

Has anyone found out what causes the fuse to the headlight switch blow out? This cuts power to the dash lights and to the running lights.
