Looking for suggestions for a quality car cover. Just spent about $5k getting my car repainted really nice and I didn't know anything about car covers so I bought one from Kirbans because everything else I have ever purchased from them was good. Unfortunately this car cover is putting little...

I'm sure this is a simple relay or something but I have no idea where it is. My A/C works and blows cold air. the bottom 3 speeds on the fan work but when I switch it to high it just blows no air at all. Tried searching forums a few times but no luck. Any ideas? Thanks in advance. I found...

I recently replaced my speed cable and I saw there was no light in the low fuel hole, so I took one off a spare dash I have and put it in the hole. The low fuel light is now on all the time. Is there a sending unit for this perhaps my car did not come with? If so can it be added so the low fuel...

I went to remove my speedo cable the other day to grease it up so it would stop bouncing and making that noise it makes. I could not get the thing apart. It appears to come in 3 pieces. I went to the local auto parts store and they only appear to sell what looks like the bottom 3rd that goes to...

Anybody out there got suggestions for replacement front fenders? Does anybdy make them that fit or am I better off doing the junk yard thing? Need one for my front passenger side. About to paint the car and the body shop tells me that fender has a decent amount of filler in it so I just assume...

I am about to have my GN painted and I want to replace the door and trunk weatherstripping at the same time. Who has had luck with their purchases in this area? I'm of course looking for best fit and best price but care more about the fit. Thanks in advance for your suggestions.

I'm looking at buying the Hooker Super Competition Ceramic Coated Headers. Does anybody have these or know of anybody using a set that has an opinion on them either way?

Recently I had my 87 GN in the shop for the following. Replacing crank sensor, front and rear main seals, oil pan gasket, timing chain cover gasket and timing chain. I had some serious oil leaks. Before I put the car in the boost PSI was 17 - 18. After I got the car back the boost goes to...

I know this is a common issue with the 87 buicks where the speedo needle bounces at the lower mph. What si the fix for this issue?

Does anyone know where I can get a brand new AC Delco A/C Compressor? If not I am also taking suggestions on quality rebuilt AC Declo compressors. Mine died and my mechanic says his supplier says they are no longer made and he can not get any.

I came across these headers for the GN and they look nice and the price is right. Has anybody purchased them and if so did they fit? they are made in china according to the replies for a few of the eBay stores. I just hate to buy them and find out they don't fit right. eBay Motors: 1986-1987...

I saw some years ago a company that made very flexible what appeared to be made of rubber oil return line from the turbo to the block. I don't want to replace the stock one with another stock one because they are such a pain to get them hooked back up to the bottom of the turbo and a flexible...

Ok let me start with I am ignorant when it comes to eletrical components. I purchased a GN August 2005 and am working slowly on making a nicer car out of it. It has a performance problem I am trying to nail down and I had a buddy hook his scan tool up but there was no power coming from the...

I have had my 87 GN for about a year. I just had the tranny rebuilt which works great but now that I can floor the gas pedal I am noticing another problem. The car seems to run fine until about 4k rpm then it seems to hit a brick wall. The RPMs don't climb and the car will not shift into 2nd...

It seems I read somewhere at one time that all the electical harnesses are there for all the options even though the car may not have come with those options. Can anyone confirm this? For example my car did not come with the passenger side lighted vanity mirror but i would like to replace my...
