1997 Buick Lesabre no power to the ac

Hi. im hoping someone can help me out with something. i have a 97 buick lasabre and the ac quit blowing cold. took it to a mechanic and he said there is no power going to the ac compressor. he had me go and buy the ac climate control and he said that would fix it. i bought one from a salvage yard and he claims that it is a bad one because it didnt turn the ac compressor on. i took it back and got another one from the same salvage yard and the mechanic says that one is also bad. is the mechanic giving me the run around? i just find it weird that i got 2 ac climate controls and both of them turned out to be bad. should i take it somewhere else?

    hi. thanks for responding so quickly. yes the mechanic said he tested the climate control. he said both were bad from testing them. thats why i came on here. i heard about this site and you guys and i have heard great things.

    there isnt a freon in it, but when it goes in, the comprssor doesnt kick on. he check the fuse and the relay and he said there is no power going to anything. you mentioned a pressure switch for the compressor. do you know where that is located. i have the car now, so i want to have an idea of what is going on when i take to another mechanic.

    hi. well i took the initiative and decided to find the issue myself. i found the hiddne fuse panel on the right side of the dash and discovered a blown 20 amp fuse. i replaced it and the compressor came back on. now i have Ac again. thanks for everything. you guys are AWESOME!!!!

That would be a good suggestion. the guy probably do not know what he is talking about.

on another thought, from where you buy them, dont they have a way to test what you are buying if it is good or bad?

original problem : no power going to the compressor.

solution: test first if there is refrigerant. there is a pressure switch in the system that would prevent the compressor form engaging.
there is a fuse that would break in case you have a faulty coil.
there is an ac relay that could break anytime.
and so many more......

the last thing to replace is the climate control....

tnx 4 using fixya,

My 1997 buick lasabre you turn th wiper on and the mortor runs but wiper dont move someone said the wipwer arms may be striped how do i gat new ones or replace them

First locate the hold down bolt on each wiper arm...try to tighten...BUT FIRST be sure the wipers are in the off...and down can verify this by turning them off while your Lesabre is running...If tightening them both does not fix...yes you will need to replace the entire wiper arm assembly...most salvage yards have plenty of parts for your popular Buick...Hope this helps...:)

What does it mean if your heater is blowing out cold air? Help I'm freezing! 97 buick lesabre

I have a 2000 having the same problem. Repair shops want almost $200 to look at it before determining the actual problem. If the heater box has to be removed, the mechanic said expect a bill of ~$600 or more.
I hope you find a solution that is more reasonable. I will keep monitoring your link.

97 Buick Lesabre-Am I crazy or do you have to unhook the engine mount to replace serpentine belt,I hope im just missing something. Thanks for any help. Don

Not the whole mount! Raise the car, remove passenger front wheel. Remove two clips that hold splash guard that is in front of the lower part of that engine mount. You'll then see the lower stud with a nut on it. Remove that nut, remove stud with a socket, then remove the spacer that was around stud between bracket and engine. That opens a gap to allow the belt to go on.

You must take it to a dealership and they will unlock it for you. There is a specific dealer code that will unlock any radio and once they do it, you pick one that you will remember. This is part of the anti theft. Hope this helps.
